Features
Functional Description
The CY7C1019B/10191B is a high-performance CMOS static
RAM organized as 131,072 words by 8 bits. Easy memory
expansion is provided by an active LOW Chip Enable (CE), an
active LOW Output Enable (OE), and three-state drivers. This
device has an automatic power-down feature that significantly
reduces power consumption when deselected.

Reading from the device is accomplished by taking Chip
Enable (CE) and Output Enable (OE) LOW while forcing Write
Enable (WE) HIGH. Under these conditions, the contents of
the memory location specified by the address pins will appear
on the I/O pins.
