256Mb: 16 Meg x 16, 8 Meg x 32 Mobile SDRAM

Functional Block Diagrams

The 256Mb SDRAM is designed to operate in 1.8V low-power memory systems. An auto

refresh mode is provided, along with a power-saving deep power-down mode. All inputs

and outputs are LVTTL-compatible.

SDRAM offers substantial advances in DRAM operating performance, including the

ability to synchronously burst data at a high data rate with automatic column-address

generation, the ability to interleave between internal banks in order to hide precharge

time, and the capability to randomly change column addresses on each clock cycle

during a burst access.
