HYI39SC2560FF

The HYI39SC2560FF are four bank Synchronous DRAM's organized as 16 MBit *8 and 8 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 Qimonda advanced 0.11 m 256-MBit DRAM process technology.

The HYI39SC2560FF 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 of the HYI39SC2560FF are supported. These devices operate with a single 3.3 V ± 0.3 V power supply. All 256-Mbit components are available in PG TSOPII54 and PG-TFBGA-54 packages.
