CY7C1006D
1-Mbit (256K x 4) Static RAM
Features
Functional Description [1]
• Pin- and function-compatible with CY7C106B/CY7C1006B
• High speed
The CY7C106D and CY7C1006D are high-performance
CMOS static RAMs organized as 262,144 words by 4 bits.
Easy memory expansion is provided by an active LOW Chip
Enable (CE), an active LOW Output Enable (OE), and tri-state
drivers. These devices have an automatic power-down feature
that reduces power consumption by more than 65% when the

10. This parameter is guaranteed by design and is not tested.
11. The internal write time of the memory is defined by the overlap of CEand WE LOW. CE and WE must be LOW to initiate a write, and the transition of either of these signals
can terminate the write. The input data set-up and hold timing should be referenced to the leading edge of the signal that terminates the write.
