Functional DescriptionThe CY62256N is a high performance CMOS
static RAMorganized as 32K words by 8 bits. Easy memory expansion
isprovided by an active LOW chip enable (CE) and active LOWoutput
enable (OE) and tristate drivers. This device has anautomatic
power-down feature, reducing the power consumptionby 99.9 percent
when deselected.An active LOW write enable signal (WE) controls
thewriting/reading operation of the memory. When CE and WEinputs
are both LOW, data on the eight data input/output pins(I/O0 through
I/O7) is written into the memory location addressedby the address
present on the address pins (A0 through A14).Reading the device is
accomplished by selecting the device andenabling the outputs, CE
and OE active LOW, while WE remainsinactive or HIGH. Under these
conditions, the contents of thelocation addressed by the
information on address pins arepresent on the eight data
input/output pins.The input/output pins remain in a high impedance
state unlessthe chip is selected, outputs are enabled, and write
enable (WE)is HIGH.For a complete list of related documentation,
