... The CY7C166 is a high-performance CMOS static RAMs organized as 16,384 by 4 bits. Easy memory expansion is provided by an active LOW Chip Enable (CE) and tri-state drivers. The CY7C166 has an active LOW Output Enable (OE) feature. This device has an automatic power-down feature, reducing the power consumption by 65% when deselected. ...

... The internal write time of the memory is defined by the overlap of CE LOW and WE LOW. Both signals must be LOW to initiate a write and either signal can terminate a write by going HIGH. The data input set-up and hold timing should be referenced to the rising edge of the signal that terminates the write. 12.
