The IS61NVP102418 Synchronous Static Random Access Memory (SSRAM) device featured on
the DE4 development board is part of the shared FMS Bus, which connects to flash memory,
SSRAM, and the MAX II CPLD (EEPM2210) System Controller. This device is a Zero-bus
turnaround (ZBT) 2MB SRAM device with a 16-bit data bus providing no bus latency
synchronous-burst SRAM with a simplified interface that fully uses available bandwidth by
removing the turnaround cycles between read and write operations.
Table 2–30
lists the SSRAM pin assignments, signal names relative to the Stratix IV GX device in
terms of I/O setting.
