The 512Mb 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.
SDRAMs offer 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.
