The storage space of the instant system is considered, for refresh purposes, to contain 512 groups of 26 bit digital words with each group containing 128 such words. Memory refresh is implemented by sequentially refreshing the groups of digital words at the rate of one group every 2.8 microseconds, giving an expected total memory refresh time of approximately 1.43 milliseconds. A particular digita...
