METHOD AND APPARATUS FOR IMPLEMENTING SRAM CELL WRITE PERFORMANCE EVALUATION |
摘要 |
A SRAM cell write performance evaluation circuit includes a SRAM core where each wordline is connected to only one bit column. A ring oscillator circuit is used to generate wordline pulses. A state machine controls operations for the SRAM cell write performance evaluation circuit including the ring oscillator circuit and the SRAM core. A control signal is applied to the state machine to select a first write operation, where the circuit simultaneously writes all the cells to a known state with wide wordlines to ensure all cells are written. Then a second write operation is selected, and all the wordlines are launched simultaneously to write the cells to the opposite state. From these write operations, a required wordline pulse width to write the cell is identified.
