The HYB39S512400/800/160AT(L) are four bank Synchronous DRAM鈥檚 organized as 4 banks x
32MBit x4, 4 banks x 16MBit x8 and 4 banks x 8Mbit x16 respectively. These synchronous 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 INFINEON鈥檚 advanced 0.14
碌m
512MBit 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 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 operates with a
single 3.3V +/- 0.3V power supply. All 512Mbit components are housed in TSOPII-54 packages.
