Description
The HY[B/I]39SC256[80/16]0F[E/F] 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 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 ± 0.3 V
power supply. All 256-Mbit components are available in PG–
TSOPII–54 and PG-TFBGA-54 packages.
