Bit-slice type large scale integrated circuit with multiple functions on a one-chip semiconductor device

摘要

Various kinds of control circuits and gate circuits are integrated on a one-chip semiconductor device to make up a bit-slice type large scale integrated circuit (LSI) with multiple functions. The gate circuits are connected with the control circuits for selecting input and output signal lines. Selecting signals are supplied to the gate circuits through the selecting lines. The gate circuits select the connection between the control circuits and the input and output lines in response to the selecting signals. The one-chip semiconductor device is particularly efficient in that it provides multiple functions without increasing the number of required terminals pins thereof.
