16M x 4-Bit Dynamic RAM (4k & 8k Refresh)
This device is a 64 MBit dynamic RAM organized 16 777 216 by 4 bits. The device is fabricated on 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)400AJ/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)400ATL parts (L-versions) have a very low power „sleep mode“ supported by Self Refresh
