16 respectively. These syn-
chronous devices achieve high speed data transfer rates for CAS latencies by employing a chip
architecture that prefetches multiple bits and then synchronizes the output data to a system clock.
The chip is fabricated with SIEMENS’ advanced 256 MBit DRAM process technology.
The device is designed to comply with all JEDEC standards set for synchronous DRAM products,
both electrically and mechanically. 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 interleave fashion allows random access operation to occur
at higher rate than is possible with standard DRAMs. A sequential and gapless data rate of is
possible depending on burst length, CAS latency and speed grade of the device.
Auto Refresh (CBR) and Self Refresh operation are supported. These devices operates with a
single 3.3 V
±
0.3 V power supply and are available in TSOPII packages.
