Abstract:
This invention discloses a dual port static random access memory (SRAM) cell, which comprises at least one inverter coupled between a positive supply voltage (Vcc) and a complementary low supply voltage (Vss) and having an input and an output terminals, at least one PMOS transistor with its gate, source and drain connected to the output terminal, Vcc and input terminal, respectively, a write port connected to the input terminal and having a write-word-line, a write-enable and a write-bit-line, and a read port connected to either the input or output terminal and having a read-word-line and a read-bit-line.
