Lattice Semiconductor
The Single Port RAM (RAM_DQ) can be configured as NORMAL, READ BEFORE WRITE or WRITE THROUGH
modes. Each of these modes affects what data comes out of the port Q of the memory during the write operation
followed by the read operation at the same memory location. The READ BEFORE WRITE attribute is supported for
x9, x18 and x36 data widths.
Additionally users can select to enable the output registers for RAM_DQ. Figures 8-7 through 8-12 show the inter-
nal timing waveforms for the Single Port RAM (RAM_DQ) with these options.
