IS46DR82560C Datasheet Ddr2 Dram

Manufacturer: ISSI (now Infineon)

Overview: IS43/46DR82560C IS43/46DR16128C 256Mx8, 128Mx16 DDR2 DRAM.

General Description

ISSI's 2Gb 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.
