Dual port memory with write assist
Abstract:
A data value is read from one port of a dual-port memory cell during a clock cycle. A WRITE assist pulse having a delay from an end-of-read signal is generated. The delay and duration of the WRITE assist pulse are optionally user-selectable. A high voltage (e.g., Vdd) is coupled to the bitlines (e.g., BL-A, BLc-A) of the first port during the WRITE assist pulse, and a low voltage value (e.g., zero) is written to the memory cell through the second port (e.g., BL-B, BLc-B) during the clock cycle.
