The HYB39S256[40/80/16]0D[C/T](L) are four bank Synchronous DRAM’s organized as 4 banks x 16 MBit x4,
4 banks x 8 MBit x8 and 4 banks x 4 Mbit 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’s advanced 0.14 µm
256-MBit 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 3.3 V
power supply. All 256-Mbit components are available in P–TSOPII–54 and P–TFBGA–54 packages.
