Data widths of 1, 2, 4, 8, 16 and 32 are supported by the MFB. Figure 10 shows the block diagram of the Pseudo Dual-Port SRAM. Write data, write address, chip select and write enable signals are always synchronous (registered). The read data and read address signals can be synchronous or asynchronous. Reset is asynchronous. All write signals share the same clock, and clock enable. All read signals share the same clock and clock enable. Reset is shared by both read and write signals. Table 6 shows the possible sources for the clock, clock enable and initialization signals for the various registers. Figure 10.
