Store IN Buffer Update

Data is entered into the latch 10, between the backing store 12 and buffer 14, at the same time data is entered into the buffer to simplify updating of the backing store.

When data is entered into the buffer 14, it is simultaneously entered into the latch 10 between the buffer 14 and backing store 12.

Then, when a free cycle occurs prior to the latch 10 being needed for some other purpose, the data stored in the latch 10 is transferred into the backing store 12 to update the data in the backing store. If the latch 10 is used prior to the transmission of data from the latch 10 into the backing store 12, the data in the latch is destroyed by such use and the backing store 12 is updated at some later time from the buffer 14. By operating the memory in this manner, the average access times during the peak activity is reduced.
