... Architecture The CY7C144AV and CY7C006AV and consist of an array of 8K and 16K words of 8 bits each of dual-port RAM cells, I/O and address lines, and control signals (CE, OE, R/W). These control pins permit independent access for reads or writes to any location in memory. To handle simultaneous writes/reads to the same location, a BUSY pin is provided on each port ...
