Lattice Semiconductor
Single-Port SRAM Mode
In Single-Port SRAM Mode the multi-function array is configured as a single-port SRAM. In this mode one ports
accesses 16,384-bits of memory. Data widths of 1, 2, 4, 8, 16 and 32 are supported by the MFB. Figure 11 shows
the block diagram of the single-port SRAM.
Write data, address, chip select and read/write signals are always synchronous (registered.) The output data sig-
nals can be synchronous or asynchronous. Reset is asynchronous. All signals share a common clock, clock
enable, and reset. Table 7 shows the possible sources for the clock, clock enable and reset signals.

Chip Select
CLK or one of the global clocks (CLK0 - CLK3). Each of these signals can
be inverted if required.
CEN or one of the global clocks (CLK1 - CLK 2). Each of these signals can
be inverted if required.
Created by the logical OR of the global reset signal and RST. RST is routed
by the multifunction array from GRP, with inversion if desired.
