GENERAL DESCRIPTION
The Micron SyncBurst SRAM family employs
high-speed, low-power CMOS designs that are fabri-
cated using an advanced CMOS process.
Micron’s 4Mb SyncBurst SRAMs integrate a
256K x 18, 128K x 32, or 128K x 36 SRAM core with ad-
vanced synchronous peripheral circuitry and a 2-bit
burst counter. All synchronous inputs pass through
registers controlled by a positive-edge-triggered single
clock input (CLK). The synchronous inputs include all
addresses, all data inputs, active LOW chip enable
NOTE: 1. JEDEC-standard MS-026 BHA (LQFP).
2. The 165-ball FBGA is not recommended for new
designs in the 4Mb density.
