The members of the family include 1-Mb (64K ×18), ½-Mb (32K x18), and ¼-Mb (16K × 18) options. All four ports may be clocked at independent frequencies from one another. Simultaneous reads are allowed for accesses to the same address location; however, simultaneous reading and writing to the same address is not allowed. Any port can write to a certain location while other ports are reading that location simultaneously, if the timing spec for port to port delay (tCCS) is met. The result of writing to the same location by more than one port at the same time is undefined. Data is registered for decreased cycle time. Clock to data valid tCD2 = 4.2 ns. Each port contains a burst counter on the input address register. After externally loading the counter with the initial address the counter will self-increment the address internally (more details to follow). The internal write pulse width is independent of the duration of the R/W input signal. The internal write pulse is self-timed to allow the shortest possi.
