SRAM Design - Write Path

The overall data path of a memory can be divided into two paths - the read path and the write path. This tutorial focuses on the write path of an SRAM. The write path has some unique requirements that the read path does not have, although there are some similarities as well. This design will include: the internal decoding for a write, the data in buffer and key control circuits along with their timing relationships. The overall integration of the write and read path will be designed thereby making up the complete data path into and out of the memory cell. A complete set of plots are provided along with a SPICE netlist that is extracted from the layout.
