The 128Mb SDRAM device uses an internal pipelined architecture to achieve high-speed
operation. This architecture is compatible with the 2n rule of prefetch architectures, but
it also enables the column address to be changed on every clock cycle to achieve a high-
speed, fully random access. Precharging one bank while accessing one of the other three
banks will hide the precharge cycles and provide seamless high-speed, random-access
operation.
The 128Mb SDRAM device is designed to operate in 3.3V or 2.5V low-power memory
systems. The 2.5V version is compatible with 1.8V I/O interface. An auto refresh mode is
provided along with a power-saving, 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 to hide precharge time, and
the capability to randomly change column addresses on each clock cycle during a burst
access.
The automotive temperature (AT) option adheres to the following specifications:
• 16ms refresh rate
• Self refresh not supported
• Ambient and case temperature cannot be less than –40°C or greater than +105°C
