PD44324362B
36M-BIT DDR II SRAM
2-WORD BURST OPERATION
Description
The
μ
PD44324092B is a 4,194,304-word by 9-bit, the
μ
PD44324182B is a 2,097,152-word by 18-bit and the
μ
PD44324362B is a 1,048,576-word by 36-bit synchronous double data rate static RAM fabricated with
advanced CMOS technology using full CMOS six-transistor memory cell.
The
μ
PD44324092B,
μ
PD44324182B and
μ
PD44324362B 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
