This device is a 64 MBit dynamic RAM organized 4 194 304 by 16 bits. The device is fabricated on an advanced second generation 64Mbit 0,35µm-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.
