36M-BIT QDR II SRAM
4-WORD BURST OPERATION
Description
The
μ
PD44325084B is a 4,194,304-word by 8-bit, the
μ
PD44325094B is a 4,194,304-word by 9-bit, the
μ
PD44325184B is a 2,097,152-word by 18-bit and the
μ
PD44325364B is a 1,048,576-word by 36-bit
synchronous quad data rate static RAM fabricated with advanced CMOS technology using full CMOS six-
transistor memory cell.
The
μ
PD44325084B,
μ
PD44325094B,
μ
PD44325184B and
μ
PD44325364B integrate unique synchronous
peripheral circuitry and a burst counter. All input registers controlled by an input clock pair (K and K#) are
latched on the positive edge of K and K#. These products are suitable for application which require
synchronous operation, high speed, low voltage, high density and wide bit configuration.
These products are packaged in 165-pin PLASTIC BGA.

Features
•
1.8 ± 0.1 V power supply
•
165-pin PLASTIC BGA (15 x 17)
•
HSTL interface
•
PLL circuitry for wide output data valid window and future frequency scaling
•
Separate independent read and write data ports with concurrent transactions
•
100% bus utilization DDR READ and WRITE operation
•
Four-tick burst for reduced address frequency
•
Two input clocks (K and K#) for precise DDR timing at clock rising edges only
•
Two output clocks (C and C#) for precise flight time
