Figure 3–16. MLABs Same-Port Read-During Write: Don’t Care Mode
For M9K and M144K memory blocks, three output choices are available in same-port
read-during-write mode: “new data” (or flow-through) or “old data”. In new data
mode, the “new data” is available on the rising edge of the same clock cycle on which
it was written. In old data mode, the RAM outputs reflect the “old data” at that
address before the write operation proceeds. In don’t care mode, the RAM outputs
“unknown values” for a read-during-write operation.
