The HYB39S256400/800/160CT(L) are four bank Synchronous DRAM's organized as 4 banks x 16MBit x4, 4 banks x 8MBit x8 and 4 banks x 4Mbit x16 respectively. These synchronous devices achieve high speed data transfer rates for CAS-latencies by employing a chip architecture that pr efetches multiple bits and then synchronizes the output data to a system clock. The chip is fabricated with INFINEON's advanced 0.17 µm 256MBit DRAM process technology. The device is designed to comply with all industry 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 a higher rate than is possible with standard DRAMs. A sequential and gapless data rate 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 operate with a single 3.3V +/- 0.3V power supply and are available in TSOPII packages.
