Register bank circuit.

摘要

A semiconductor device including a register bank circuit comprises register array means (51) for storing data, said register array means having a matrix structure which is formed of a plurality of banks (BJ) arranged in a row of the matrix structure and a plurality of registers (RK) arranged in a column thereof, bank selector means (53, 54) for selecting one (e.g., B1) of said banks (BJ) while the one to be selected is specified, register selector means (55, 56) for selecting one (e.g., R2) of said registers (RK) in the one bank (B1) selected by said bank selector means (54), so that the selected register (R2) is coupled to a bus (57).
