PRELIMINARY INFORMATION
Overview
The IS66/67WVE4M16EALL/BLL/CLL is an integrated memory device containing 64Mbit Pseudo Static
Random Access Memory using a self-refresh DRAM array organized as 4M words by 16 bits. The device
includes several power saving modes : Partial Array Refresh mode where data is retained in a portion of
the array and Deep Power Down mode. Both these modes reduce standby current drain. The die has
separate power rails, VDDQ and VSSQ for the I/O to be run from a separate power supply from the device
core.
