Design and implementation of dual port SRAM memory architecture using MOSFET's

Dual port memory cell is the multiport memory cell that provides required access to multi-processor applications. It uses two additional pass transistors, bit line pair and a word line to provide much needed simultaneous access. Each SRAM cell is accessed by dual ports with devoted word and bit lines to each. Single port SRAM allows access to only single address of a memory cell at a time during each clock pulse but dual port overcomes this drawback and allows concurrent read or write access at different addresses. Thus the efficiency is almost doubled by using dual port RAM. The most important benefit of dual port RAM is that they will not have limitations of access between the two ports, as each processor can be made to operate at different clock frequencies.
