Mobile DRAM
HyperRAM
An improved version of the Pseudo SRAM memories, consisting of a DRAM macro core with a traditional asynchronous SRAM interface, characterized by higher speed and smaller form factor size.
* Status: P - mass production, S - samples, UD - under development, N - not recommended for new design.
