Abstract

A bidirectional elastic store circuit comprises an elastic store portion (1) having a node (A) for writing data and a node (B) for reading out data, an input terminal (8) and an output terminal (9) for data communication in a first direction, an input terminal (10) and an output terminal (11) for data communication in a second direction opposite to the first direction, a group of logical circuits (13) for selecting either the input terminals (8, 10) and a group of logical circuits (14) for selecting either the output terminals (9, 11). At the time of data communication in the first direction, a switching signal EN1/EN2 applied from an input terminal (12) becomes high, so that the input terminal (8) and the output terminal (9) are coupled to the elastic store portion (1) through the nodes (A) and (B), respectively. On the other hand, at the time of data communication in the second direction, the switching signal EN1/EN2 becomes low, so that the input terminal (10) and the output terminal ( 11) are coupled to the elastic store portion (1) through the nodes (A) and (B), respectively.
