Abstract
A pseudo dual port (PDP) memory is disclosed having a write driver that selectively precharges only one of a bit line and a complement bit line in a bit line pair responsive to a bit value to be written into an accessed bitcell while discharging a remaining one of the bit line and the complement bit line. In this fashion, the cleanup time between a read operation and a write operation during a read/write clock cycle is advantageously reduced.
