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.
