GENERAL DESCRIPTION (continued)
and DQPc; BWd# controls DQd pins and DQPd. GW#
LOW causes all bytes to be written. Parity pins are only
available on the x18 and x36 versions.
This device incorporates a single-cycle deselect fea-
ture during READ cycles. If the device is immediately
deselected after a READ cycle, the output bus goes to a
High-Z state tKQHZ nanoseconds after the rising edge
of clock.
Micron’s 1Mb SyncBurst SRAMs operate from a +3.3V
power supply, and all inputs and outputs are TTL-com-
patible. The device is ideally suited for Pentium and
PowerPC pipelined systems and systems that benefit
from a very wide, high-speed data bus. The device is
also ideal in generic 16-, 18-, 32-, 36-, 64- and 72-bit-
* Pins 49 and 50 are reserved for address expansion.
** No Connect (NC) is used on the x32 version. Parity (DQPx) is used on the x36 version.
