8M x 8-DRAM
This device is a 64 MBit dynamic RAM organized 8 388 608 by 8 bits. The device is fabricated in an
advanced second generation 64Mbit 0,35
µm
CMOS silicon gate process technology. The circuit
and process design allow this device to achieve high performance and low power dissipation. This
DRAM operates with a single 3.3 +/-0.3V power supply and interfaces with either LVTTL or
LVCMOS levels. Multiplexed address inputs permit the HYB 3164(5)800AJ/AT to be packaged in a
400mil wide SOJ-32 or TSOP-32 plastic package. These packages provide high system bit
densities and are compatible with commonly used automatic testing and insertion equipment. The
HYB3164(5)800ATL parts (L-versions) have a very low power „sleep mode“ supported by Self
Refresh
