3.2.2. Mixed-Port Read-During-Write Mode

The mixed-port read-during-write mode applies to simple and true dual-port RAM modes where two ports perform read and write operations on the same memory address using the same clock—one port reading from the address, and the other port writing to it.

Table 10.  Output Modes for RAM in Mixed-Port Read-During-Write Mode
Output Mode Description
"old data"

A read-during-write operation to different ports causes the RAM output to reflect the “old data” value at the particular address.

"don't care"

The RAM outputs “don’t care” or “unknown” value.
