Abstract

PURPOSE:To detect the completion of data tansfer without using an end code by providing one redundancy bit to each of (m) stages of a serial memory, and then applying an OR signal regarding a strobe signal and a data end signal during data writing operation. CONSTITUTION:To a serial memory 1 wherein (n)-bit data are stored as (m) stages, redundancy bits 2 of one-bit constitution are added as (m) stages. During data writing operation, an input ready signal IR is supplied from the memory 1 to a data transmission side, and input data DI1-DIn and a strobe signal ST are applied to an OR gate 3. The gate 3 supplies a shift-in signal SI to the memory 1 and the input data are shifted to right successively. Once transmitted data are all written, a transfer end signal E is applied to the 1st stage of the bit 2 and the gate 3 to perform right shifting operation. When a shift-out signal SO is applied from a reception side, output data DO1-DOn are sent out and after all the data are outputted, the output of the (m) stages of the bits 2 and an output ready signal OR are applied to an AND gate 4, which supplies an end detection signal ED to the reception side.
