US Patent 9129707 Dual port SRAM with dummy read recovery

An integrated includes a dual port memory cell such as a SRAM cell. A first port dummy read recovery block couples the first port complementary bit line to a high voltage supply node during a write logic low operation to the data node through the second port bit line, and couples the first port bit line to a high voltage supply node during a write logic low operation to the complementary data node through the second port complementary bit line. A second port dummy read recovery block couples the second port complementary bit line to a high voltage supply node during a write logic low operation to the data node through the first port bit line, and couples the second port bit line to a high voltage supply node during a write logic low operation to the complementary data node through the first port complementary bit line.
