Data aware write scheme for SRAM |
摘要 |
Approaches for providing write-assist for a Static Random Access Memory (SRAM) array are provided. A circuit includes a control circuit connected to a cell in a SRAM array. The control circuit is configured to: apply a first voltage to a first pull down transistor of the cell during a write operation to the cell; and apply a second voltage, different than the first voltage, to a second pull down transistor of the cell during the write operation. |

1. A circuit, comprising:
a control circuit connected to a cell in a Static Random Access Memory (SRAM) array, wherein the control circuit is configured to:
apply a first voltage to a first pull down transistor of the cell during a write operation to the cell; andapply a second voltage, different than the first voltage, to a second pull down transistor of the cell during the write operation,wherein a trigger signal causes the second voltage to be different than the first voltage, the trigger signal being based on a bit-switch signal that controls a bit-switch connected to the cell. |
