IS43DR16320D Datasheet - ISSI

IS43DR16320D DDR2 DRAM

ISSI's 512Mb DDR2 SDRAM uses a double-data-rate architecture to achieve high-speed operation. The double-data rate architecture is essentially a 4n-prefetch architecture, with an interface designed to transfer two data words per clock cycle at the I/O balls. ADDRESS TABLE Parameter 64M x 8 32M x.

IS43DR16320D Features

* Vdd = 1.8V ±0.1V, Vddq = 1.8V ±0.1V

* JEDEC standard 1.8V I/O (SSTL_18-compatible)

* Double data rate interface: two data transfers per clock cycle

* Differential data strobe (DQS, DQS)

* 4-bit prefetch architecture

* On chip DLL to align DQ and DQS
