Abstract

PURPOSE: To select the switch system by providing a 2-way operation channel memory having two sets of a memory writing an input data sequentially and a memory reading the data sequentially and a one-way operation channel memory repeating alternately the write/read.
CONSTITUTION: A channel memory 10 has two sets of memories in the inside and one set is in the mode writing sequentially a channel data from an input terminal 1 according to the address of an address generating circuit 50. Further, the other set is in the mode reading the talking data according to a control data from a control memory 40. Then each mode is to be switched. The channel memory 20 is so constituted that the mode writing a data from the terminal 1 and the mode reading the data according to the control data of the memory 40 are switched alternately. The data read from the memories 10, 20 is switched by a selector 30 and outputted to a terminal 3. The switch system is switched by selecting the memories 10, 20.
