Both have a fast dedicated connection to the CPU. However, the overhead to implement the TCM is far less than a cache. Typically TCM is found on lower-end (deeply embedded probably Cortex-M) ARM devices.

The amount of cycles that it takes to activate the next bank of memory. It is the opposite of tRAS. The lower the timing, the better the performance, but it can cause instability. tRFC Timing: Row Refresh Cycle Timing. This determines the amount of cycles to refresh a row on a memory bank. bmw speyer https://sproutedflax.com
