Abstract
An apparatus and method for providing efficient floor planning, power, and performance tradeoffs of memory accesses. A dual read port and single write port memory bit cell uses two asymmetrical read access circuits for conveying stored data on two read bit lines. The two read bit lines are pre-charged to different voltage reference levels. The layout of the memory bit cell places the two read bit lines on an opposed edge from the single write bit line. The layout uses a dummy gate placed over both p-type diffusion and n-type diffusion between the edges. The layout has a same number of p-type transistors as n-type transistors despite using asymmetrical read access circuits. The layout also has a contacted gate pitch that is one more than the number of p-type transistors.
