Abstract

PURPOSE: To reduce the access timing by dividing the memory unit of time switch into a plural number of blocks and by allowing the plural number of blocks to have an access in parallel on the sequential side.
CONSTITUTION: A time slot which ignores once in n time slots is generated in the row of information on incoming-highway HWLI and this timing position is decoded by decoder DEC and applied to the reading timing. At this time, R/W signal becomes "1", an address on SQ side common to memory unit blocks M1∼Mn is selected by selector SEL, one side of each OR circuit becomes "1", BS of each memory unit block becomes "1" without depending on the output of decoder DECB, thus making the total memory output effective and inputting the output into latch circuits L1∼Ln and, then, holding it by reading pulse Rp. Therefore, a plural number of memory unit blocks can be read in parallel by one Rp.
