INTRODUCTION
The UT8SDMQ64M40 and UT8SDMQ64M48 are high
performance, highly integrated Synchronous Dynamic Random
Access Memory (SDRAM) multi-chip modules (MCMs). Total
module density is 2,684,354,560 bits for the 2.5G device and
3,221,225,472 bits for the 3G device. Each bit bank is organized
as 8192 rows by 2048 columns.
Read and write accesses to the DRAM are burst oriented;
accesses start at a selected location and continue for a
programmed number of locations in a programmed sequence.
The programmable READ and WRITE burst lengths (BL) are
1, 2, 4, or 8 locations, or the full page, with a burst terminate
option.
Aeroflex’s SDRAMs are designed to operate at 3.3V. An auto-
refresh mode is provided, along with a power-saving, power-
down mode. All inputs and outputs are LVTTL compatible.
SDRAMs offer significant advances in DRAM operating
execution, including the capability to synchronously burst data
at a high data rate with automatic column-address generation,
to interleave between internal banks to mask precharging time,
and to randomly change column addresses on each clock cycle
during a burst access.
