Write Access

Write-Through Mode:

Writing to external memory is performed regardless of whether or not

there is a cache hit. The write address output to the cache address bus is used for comparison to the
tag address of the cache’s address array. If they match, the write data output to the cache data bus
in the following cycle is written to the cache data array. If they do not match, nothing is written to
the cache data array. The write address is output to the internal address bus 1 cycle later than the
cache address bus. The write data is similarly output to the internal data bus 1 cycle later than the
cache data bus. The CPU waits until the writes on the internal buses are completed (figure 8.5).
