Title:
双方向シフトレジスタの制御装置及び双方向シフトレジスタ回路
Document Type and Number:
Japanese Patent JP3998676
Kind Code:
B2
Abstract:
A bi-directional shift register circuit comprising, a plurality of shift register stages, each having an input and an output terminal, and a bi-directional shift controller circuit associated with each of said shift register stages is disclosed. The bi-directional shift controller circuit comprises a first input connected to a output terminal of a first shift register stage and a second input connected to a output terminal of a second shift register stage. Means to apply a first and a second control voltage, wherein said first and second control voltage are different, and a combinatorial circuit responsive to said first and second control voltages to apply an indication of an input received from either said first shift register or said second shift register to said corresponding shift register input terminal. The combinatorial circuit configuration is that of a NOR gate or a NAND gate.
