Description
The 256MBit Mobile-RAM is a new generation of low power, four bank synchronous DRAM organized as
4 banks x 4 Mbit x 16 with additional features for mobile applications. The synchronous Mobile-RAM achieves
high speed data transfer rates by employing a chip architecture that prefetches multiple bits and then synchronizes
the output data to a system clock.
The device adds new features to the industry standards set for synchronous DRAM products. Parts of the memory
array can be selected for Self-Refresh and the refresh period during Self-Refresh is programmable in 4 steps
