Table 10-4. Single Port RAM Attributes for LatticeXP2
The Single Port RAM (RAM_DQ) can be configured as NORMAL or WRITE THROUGH modes. Each of these
modes affects the data coming out of port Q of the memory during the write operation followed by the read opera-
tion at the same memory location.
Additionally, users can select to enable the output registers for RAM_DQ. Figures 10-6-10-9 show the internal tim-
ing waveforms for the Single Port RAM (RAM_DQ) with these options.
