MODULE

FEATURES

• JEDEC- and industry-standard pinout in a 72-pin,

• 16MB (4 Meg x 36) and 32MB (8 Meg x 36) parity

• High-performance CMOS silicon-gate process

• Single 5V 10% power supply

• All inputs, outputs and clocks are TTL-compatible

• Refresh modes: RAS#-ONLY, CAS#-BEFORE-RAS#

• 2,048-cycle refresh distributed across 32ms

• FAST PAGE MODE (FPM) access cycle

• Multiple RAS# lines allow x18 or x36 widths

GENERAL DESCRIPTION

16MB and 32MB solid-state memories organized in a x36

configuration. During READ or WRITE cycles, each bit is

uniquely addressed through the 22 address bits, which are

entered 11 bits (A0 -A10) at a time. RAS# is used to latch the

first 11 bits and CAS# the latter 11 bits. A READ or WRITE

cycle is selected with the WE# input. A logic HIGH on WE#

dictates READ mode, while a logic LOW on WE# dictates

WRITE mode. During a WRITE cycle, data-in (D) is latched

by the falling edge of CAS#. Since WE# goes LOW prior to

CAS# going LOW, the output pin(s) remain open (High-Z)

until the next CAS# cycle.
