PURPOSE:To contract the sizes of circuits and to simultaneously obtain the data of plural delay variables by connecting a data shifting means in addition to memory cells arranged in plural rows and an address control means. CONSTITUTION:The delay device has the data shifting means 40 for transferring data read out from each row of the memory cells 1 to 15 arranged in plural rows to the memory cell of the succeeding row. Thereby, the data are successive ly transferred from the 1st row 1 to 5 in the memory cells 1 to 15 arranged in plural rows to the final row 11 to 15, external input data are written only in the memory cells 1 to 5 in the 1st row and external output data are read out only from the memory cells 11 to 15 in the final row, so that the use of an I/O selecting circuit network and a selection control circuit network can be made unnecessary. Consequently, the data of plural different delay variables can be simultaneously obtained from the compact delay device whose circuit size is reduced. |
