Table 9-3. Single Port RAM Attributes for MachXO
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.
Additionally, users can select to enable the output registers for RAM_DQ. Figures 9-9 to 9-14 show the internal tim-
ing waveforms for the Single Port RAM (RAM_DQ) with these options.
