摘要:
An apparatus includes a first read port, a second read port, a write port, and at least one storage latch. A width of a bit cell that includes the first read port, the second read port, and the write port is greater than twice a contacted poly pitch (CPP) associated with the bit cell. For example, a bit cell may be a 3-port static random access memory (SRAM) bit cell that is compatible with self-aligned double patterning (SADP) processes and that can be manufactured using semiconductor manufacturing processes of less than 14 nanometers (nm).
