3.6. Memory
1Gbit Flash & 256Mbit SDRAM employed on KE770with 16 bit parallel data bus thru ADD(0) ~
ADD(24). The 256Mbit Capulet Wireless Flash memory with LPSDRAM stacked device family offers
multiple high-performance solutions. The Capulet flash die is manufactured on 90 nm process
technology. It delivers 108 MHz synchronous burst and page-mode read rates with supports multi-
partitioning with Read-While-Write (RWW) or Read-While-Erase (RWE) dual operations. The
LPSDRAM is a high-performance volatile memory operating at speeds up to 104 MHz with
configurable burst lengths.
