Abstract

PURPOSE:To reduce the number of elements to realize a simple and miniature constitution for a two-way shift register, by connecting two pairs of clock synchronous logical circuits in a prescribed way and providing a transmission gate at the end of connection to form a 1-bit circuit. CONSTITUTION:One output is connected to the other input among two pairs of clocked inverters 21 and 22 each other, and a transmission gate 24 is connected to a connecting point 23 to obtain a circuit equivalent to a bit of a shift register. When the gate 24 is turned on by a clock phi1, the data is shifted to right via the inverter 21. In this case, a clock phiL is set at zero and thus the output of the inverter 22 is set at a high impedance without affecting the transfer data. In the same way, the data is shifted to left via the inverter 22 when the transmission gate conducts to the bit circuit of a digit right-above. As a result, a number of gate circuits is elminated to obtain a two-way shift register having a reduced number of elements and a small occupied area with a simple and miniature constitution.
