Description
The AS4C32M16SA is a four bank Synchronous DRAM organized as 4 banks x 8Mbit x 16. The
AS4C32M16SA achieves high speed data transfer rates up to 143 MHz by employing a chip
architecture that prefetches multiple bits and then synchronizes the output data to a system clock.
All of the control, address, data input and output circuits are synchronized with the positive edge of
an externally supplied clock.
Operating the four memory banks in an inter-leaved fashion allows random access operation to
occur at higher rate than is possible with standard DRAMs. A sequential and gapless data rate of up
to 143 MHz is possible depending on burst length, CAS latency and speed grade of the device.
