Features
Functional Description
The CY7C1021B/10211B is a high-performance CMOS static
RAM organized as 65,536 words by 16 bits. This device has
an automatic power-down feature that significantly reduces
power consumption when deselected.
Note:
1. For best-practice recommendations, please refer to the Cypress application note “System Design Guidelines” on http://www.cypress.com.

Writing to the device is accomplished by taking Chip Enable
(CE) and Write Enable (WE) inputs LOW. If Byte Low Enable
(BLE) is LOW, then data from I/O pins (I/O

Reading from the device is accomplished by taking Chip
Enable (CE) and Output Enable (OE) LOW while forcing the
Write Enable (WE) HIGH. If Byte Low Enable (BLE) is LOW,
then data from the memory location specified by the address
pins will appear on I/O
LOW, then data from memory will appear on I/O

description of read and write modes.
The input/output pins (I/O
high-impedance state when the device is deselected (CE
HIGH), the outputs are disabled (OE HIGH), the BHE and BLE
are disabled (BHE, BLE HIGH), or during a write operation (CE
LOW, and WE LOW).
The CY7C1021B/10211B is available in standard 44-pin
