lists the RLDRAM II CIO component reference and manufacturing
information.
SSRAM
The SSRAM device consists of a single standard synchronous SRAM, providing 2-MB
memory interface with a 36-bit data bus. This device is part of the shared FSM bus
which connects to the flash memory, SSRAM, and MAX
II CPLD EPM2210 System
Controller. The device speed is 250-MHz single-data-rate.
