Abstract
A static random-access memory (SRAM) module includes a column select (RSEL) driver coupled to an input/output (I/O) circuit by an RSEL line. The I/O circuit is configured to read bit line signals from a bit cell within the SRAM module. During a read operation, the RSEL driver pulls the RSEL line to zero in order to cause p-type metal-oxide-semiconductors (PMOSs) within the I/O circuit to sample the bit line signals output by the bit cell. In response, an aggressor driver drives the RSEL line to a negative voltage, thereby reducing the resistance of the PMOSs within the I/O circuit.
