During a write operation, the RAM output behavior is configurable. If you use the
read-enable signal and perform a write operation with the read enable deactivated,
the RAM outputs retain the values they held during the most recent active read
enable. If you activate read enable during a write operation, or if you do not use the
read-enable signal at all, the RAM outputs show the “new data” being written, the
“old data” at that address, or a “don’t care” value.
