## Current vs. Time Graph with Varying Voltage and Current Conditions ### Overview The image is a line graph showing the current (in Amperes) as a function of time (in seconds). The graph illustrates how the current changes over time under different voltage and current conditions, which are indicated by numbered, colored vertical bands. The conditions alternate between applying a "perturb" voltage (VM) and setting the voltage with varying current limits (NVM). ### Components/Axes * **Y-axis:** Current (A), with a scale from 0 to 2x10^-4 A. Major tick marks are at 0, 5x10^-5, 1x10^-4, 1.5x10^-4, and 2x10^-4 A. * **X-axis:** Time (secs), with a scale from 0 to 0.6 seconds. Major tick marks are at 0, 0.1, 0.2, 0.3, 0.4, 0.5, and 0.6 seconds. * **Data Series:** A single data series represented by a blue line with square markers, showing the current's evolution over time. * **Vertical Bands:** Nine vertical bands, each with a different background color, numbered 1 through 9. Each band corresponds to a specific voltage/current condition described in the legend to the right of the graph. * **Legend (Right Side):** A numbered list describing the voltage and current conditions for each vertical band. 1. NVM: I = 1 nA, read = 0.1 V, 5 ms 2. NVM: Vset = 5 V, 5 ms, Icc = 1 µA, read = 0.1 V, 5 ms 3. VM: Vperturb = 0.3 V, 5 ms 4. NVM: Vset = 5 V, 5 ms, Icc = 60 µA, read = 0.1 V, 5 ms 5. VM: Vperturb = 0.3 V, 5 ms 6. NVM: Vset = 5 V, 5 ms, Icc = 120 µA, read = 0.1 V, 5 ms 7. VM: Vperturb = 0.3 V, 5 ms 8. NVM: Icc = Vset = 5 V, 5 ms, 180 µA, read = 0.1 V, 5 ms 9. VM: Vperturb = 0.3 V, 5 ms ### Detailed Analysis * **Band 1 (Blue):** NVM, I = 1 nA. The current is approximately 0 A. * **Band 2 (Green):** NVM, Vset = 5 V, Icc = 1 µA. The current increases to approximately 2x10^-5 A. * **Band 3 (Yellow):** VM, Vperturb = 0.3 V. The current remains around 2x10^-5 A, with some fluctuations. * **Band 4 (Green):** NVM, Vset = 5 V, Icc = 60 µA. The current increases to approximately 6x10^-5 A. * **Band 5 (Yellow):** VM, Vperturb = 0.3 V. The current remains around 6x10^-5 A, with some fluctuations. * **Band 6 (Green):** NVM, Vset = 5 V, Icc = 120 µA. The current increases to approximately 1.2x10^-4 A. * **Band 7 (Yellow):** VM, Vperturb = 0.3 V. The current remains around 1.2x10^-4 A, with some fluctuations. * **Band 8 (Pink):** NVM, Icc = Vset = 5 V, 180 µA. The current increases to approximately 1.8x10^-4 A. * **Band 9 (Purple):** VM, Vperturb = 0.3 V. The current remains around 1.8x10^-4 A, with some fluctuations. ### Key Observations * The current increases significantly when the voltage is set (Vset) with increasing current limits (Icc). * The current remains relatively stable, with minor fluctuations, when the perturb voltage (Vperturb) is applied. * The current levels off at different plateaus corresponding to the different Icc values. ### Interpretation The graph demonstrates the effect of applying different voltage and current conditions to a non-volatile memory (NVM) device. Setting the voltage (Vset) with increasing current limits (Icc) causes the current to increase in a stepwise manner, indicating a change in the device's resistance. Applying a perturb voltage (Vperturb) does not significantly alter the current, suggesting that it does not cause a significant change in the device's state. The data suggests that the NVM device's resistance can be controlled by varying the Vset and Icc parameters. The plateaus observed during the Vperturb phases indicate that the device maintains its state until a new Vset is applied.

\n ## Chart: Current vs. Time for NVM Perturbation ### Overview The image presents a chart illustrating the relationship between current (in Amperes) and time (in seconds) under different perturbation conditions. The chart displays nine distinct data series, each corresponding to a specific perturbation step, labeled 1 through 9. The data appears to represent the current response of a Non-Volatile Memory (NVM) device to varying stimuli. ### Components/Axes * **X-axis:** Time (secs), ranging from 0 to 0.6 seconds. Marked with tick intervals at 0, 0.1, 0.2, 0.3, 0.4, 0.5, and 0.6. * **Y-axis:** Current (A), ranging from 0 to 2x10^-4 A (200 µA). Marked with tick intervals at 5x10^-5 A, 1x10^-4 A, and 2x10^-4 A. * **Data Series:** Nine distinct lines, each representing a different perturbation step, labeled 1-9. Each line is represented by a series of data points connected by lines. * **Legend:** Located to the right of the chart, listing the conditions for each data series. ### Detailed Analysis The chart shows a series of current rises and plateaus, each corresponding to a different perturbation step. The data points are plotted as small squares. * **Series 1 (Green):** Starts at approximately 0 seconds and 5x10^-5 A. The current increases steadily to approximately 1.8x10^-4 A at 0.1 seconds, then plateaus. * **Series 2 (Light Green):** Begins at 0.1 seconds and 1.8x10^-4 A. The current drops to approximately 5x10^-5 A at 0.2 seconds, then rises again to approximately 1.8x10^-4 A at 0.25 seconds, then plateaus. * **Series 3 (Yellow):** Starts at 0.2 seconds and 5x10^-5 A. The current remains relatively constant at approximately 5x10^-5 A until 0.3 seconds. * **Series 4 (Light Yellow):** Begins at 0.3 seconds and 5x10^-5 A. The current increases rapidly to approximately 1.8x10^-4 A at 0.35 seconds, then plateaus. * **Series 5 (Orange):** Starts at 0.35 seconds and 1.8x10^-4 A. The current drops to approximately 5x10^-5 A at 0.4 seconds, then rises again to approximately 1.8x10^-4 A at 0.45 seconds, then plateaus. * **Series 6 (Light Orange):** Begins at 0.4 seconds and 5x10^-5 A. The current increases rapidly to approximately 1.8x10^-4 A at 0.45 seconds, then plateaus. * **Series 7 (Red):** Starts at 0.45 seconds and 5x10^-5 A. The current remains relatively constant at approximately 5x10^-5 A until 0.5 seconds. * **Series 8 (Light Red):** Begins at 0.5 seconds and 5x10^-5 A. The current increases rapidly to approximately 1.8x10^-4 A at 0.55 seconds, then plateaus. * **Series 9 (Purple):** Starts at 0.55 seconds and 5x10^-5 A. The current remains relatively constant at approximately 5x10^-5 A until 0.6 seconds. **Legend Details:** 1. NVM: I = 1 nA, read = 0.1 V, 5 ms 2. NVM: V_set = 5 V, 5 ms, I_cc = 1 µA, read = 0.1 V, 5 ms 3. VM: V_perturb = 0.3 V, 5 ms 4. NVM: V_set = 5 V, 5 ms, I_cc = 60 µA, read = 0.1 V, 5 ms 5. VM: V_perturb = 0.3 V, 5 ms 6. NVM: V_set = 5 V, 5 ms, I_cc = 120 µA, read = 0.1 V, 5 ms 7. VM: V_perturb = 0.3 V, 5 ms 8. NVM: I_cc = V_set = 5 V, 5 ms, 180 µA, read = 0.1 V, 5 ms 9. VM: V_perturb = 0.3 V, 5 ms ### Key Observations * The chart demonstrates a cyclical pattern of current increase followed by a plateau. * The current increases are generally rapid, while the plateaus are sustained. * The perturbation steps 3, 5, 7, and 9 show a relatively constant current level. * The NVM steps (1, 2, 4, 6, 8) show a similar pattern of current increase and plateau, but with varying current levels. * The current levels appear to be correlated with the I_cc values in the NVM steps. Higher I_cc values generally correspond to higher current plateaus. ### Interpretation The data suggests that the NVM device exhibits a current response that is sensitive to the applied perturbation conditions. The alternating steps of NVM and VM perturbation likely represent a read/write cycle or a similar operation. The current increases likely correspond to the writing process, while the plateaus represent the reading process. The varying I_cc values in the NVM steps indicate that the current response can be controlled by adjusting the current compliance. The VM perturbation steps, with a constant V_perturb, likely serve as a baseline or control condition. The cyclical nature of the data suggests that the device is capable of repeated read/write cycles. The data could be used to characterize the performance of the NVM device and optimize its operating parameters. The consistent V_perturb values across steps 3, 5, 7, and 9 suggest a consistent baseline for comparison against the NVM steps.

## Line Graph: Current Response Over Time Under Various Electrical Conditions ### Overview The image is a line graph depicting current (in amperes) over time (in seconds) under nine distinct experimental conditions. Vertical colored bars segment the time axis into intervals, each labeled with a number and experimental condition. Data points (blue squares) are plotted within these intervals, showing current trends. A legend on the right maps colors to specific conditions. ### Components/Axes - **X-axis (Time)**: Labeled "Time (secs)", spanning 0 to 0.6 seconds in 0.1-second increments. - **Y-axis (Current)**: Labeled "Current (A)", ranging from 0 to 2×10⁻⁴ A in 5×10⁻⁵ A increments. - **Legend**: Positioned on the right, associating colors with experimental conditions (e.g., "NVM: I = 1 nA, read = 0.1 V, 5 ms"). - **Data Points**: Blue squares connected by lines in some intervals (e.g., bars 7–9). ### Detailed Analysis 1. **Time Intervals and Conditions**: - **Bar 1 (0–0.1s)**: Light blue. Condition: NVM, I = 1 nA, read = 0.1 V, 5 ms. - **Bar 2 (0.1–0.2s)**: Teal. Condition: NVM, V_set = 5 V, 5 ms, I_cc = 1 μA, read = 0.1 V, 5 ms. - **Bar 3 (0.2–0.3s)**: Light green. Condition: VM, V_perturb = 0.3 V, 5 ms. - **Bar 4 (0.3–0.4s)**: Teal. Condition: NVM, V_set = 5 V, 5 ms, I_cc = 60 μA, read = 0.1 V, 5 ms. - **Bar 5 (0.4–0.5s)**: Light green. Condition: VM, V_perturb = 0.3 V, 5 ms. - **Bar 6 (0.5–0.6s)**: Teal. Condition: NVM, V_set = 5 V, 5 ms, I_cc = 120 μA, read = 0.1 V, 5 ms. - **Bar 7 (0.6–0.7s)**: Light green. Condition: VM, V_perturb = 0.3 V, 5 ms. - **Bar 8 (0.7–0.8s)**: Teal. Condition: NVM, I_cc = V_set = 5 V, 5 ms, 180 μA, read = 0.1 V, 5 ms. - **Bar 9 (0.8–0.9s)**: Light green. Condition: VM, V_perturb = 0.3 V, 5 ms. 2. **Data Trends**: - **Early Intervals (Bars 1–3)**: Current remains near baseline (~1×10⁻⁵ A) with minor fluctuations. - **Mid-Intervals (Bars 4–6)**: Gradual increase in current, reaching ~1.5×10⁻⁴ A by Bar 6. - **Late Intervals (Bars 7–9)**: Sharp rise in current, peaking at ~2×10⁻⁴ A in Bar 9. 3. **Color Consistency**: - All data points (blue squares) align with the legend’s "VM" or "NVM" conditions, matching the bar colors (e.g., teal for NVM, light green for VM). ### Key Observations - **Baseline Stability**: Early intervals show minimal current variation, suggesting stable initial conditions. - **Gradual Activation**: Mid-intervals exhibit a linear increase in current, possibly indicating a charging or activation process. - **Threshold Response**: Late intervals show a sharp current spike, implying a critical threshold (e.g., voltage or current) is reached. - **Condition-Specific Behavior**: "VM" conditions (light green bars) consistently show higher current than "NVM" (teal bars) in later intervals. ### Interpretation The graph demonstrates how electrical perturbations (e.g., voltage settings, current injections) influence current response over time. The sharp increase in later intervals suggests a nonlinear response, potentially indicating a switching mechanism or saturation effect. The consistent use of 5 ms read times and 0.1 V read voltage across conditions implies standardized measurement protocols. The "VM" conditions (voltage modulation) appear to drive higher current than "NVM" (current injection), highlighting the role of voltage in modulating the system’s behavior. The data may reflect a device’s dynamic response to electrical stimuli, with implications for applications like neuromorphic computing or sensor arrays.
