Abstract:
A serial data transfer device for serially transferring data comprising:an input terminal to which a serial data is inputted;a first temporary memory for temporarily storing the serial data supplied from the input terminal;a first memory for storing the data supplied from the first temporary memory;a second temporary memory for temporarily storing the serial data supplied from the input terminal;a second memory for storing the data supplied from the second temporary memory;a first transfer state detecting circuit for generating a first control signal indicative of that the serial data supplied from the input terminal is being transferred;a second transfer state detecting circuit for generating a second control signal indicative of that the serial data supplied from the input terminal is being transferred;a control circuit for deciding that the first and the second control signal have not arrived in response to the arrival of a transfer command signal, thereby transferring the data from the first temporary memory to the first memory and transferring the data from the second temporary memory to the second memory, whereby in response to the transfer command signal, the data are simultaneously transferred to said first memory and said second memory.
