GENERAL DESCRIPTION

The Micron^®Zero Bus Turnaround^™(ZBT^™) SRAM

family employs high-speed, low-power CMOS designs

using an advanced CMOS process.

2.5V I/O

256K x 18

MT55L128V32P1

MT55L128V36P1

The S^MARTZBT feature enhances the ability of the

SRAM to run in systems with minimal transition time

on the data bus, whether using multiple SRAMs or

complementing ASIC designs.

• Package

100-pin TQFP

119-pin, 14mm x 22mm BGA

Micron’sSMART ZBTfeatureallowsthe^tKHQX1(clock

HIGH tooutputvalid)toadapttothesystemclock, thus

reducing contention issues. The S^MARTZBT will drive

the bus turn-on later than the traditional ZBT.

*SMART ZBT option available.
