18M-BIT DDRII SRAM
2-WORD BURST OPERATION
Description
The
μ
PD44164082A is a 2,097,152-word by 8-bit, the
μ
PD44164092A is a 2,097,152-word by 9-bit, the
μ
PD44164182A
is a 1,048,576-word by 18-bit and the
μ
PD44164362A is a 524,288-word by 36-bit synchronous double data rate static
RAM fabricated with advanced CMOS technology using full CMOS six-transistor memory cell.
The
μ
PD44164082A,
μ
PD44164092A,
μ
PD44164182A and
μ
PD44164362A 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 package (13 x 15)
•
HSTL interface
•
PLL circuitry for wide output data valid window and future frequency scaling
•
Pipelined double data rate operation
