Title: Integrated memory circuit
Inventor: RONARUDO KURAAKU GETSUDESU
IPC: G11C16/06
Filed: 1989-02-15
Abstract: PURPOSE: To simplify the constitution of a switch and moreover to surely operate regardless of a crosstalk on a clock line by making a first and second transistor in a memory circuit an enhancement type transistor. CONSTITUTION: This memory circuit is provided with the enhancement type second transistor T2 , the enhancement type first transistor T3 and capacitances C1 , C2 . In order to transfer an electric charge with the existance of high clock signals ϕ, a voltage in the control electrode of a transistor T3 , which is the sum of a voltage with the existance of the electric charge (capacitance C1 ) in a connecting point B and high clock signals, is necessitated to rise by one threshold voltage higher than a voltage in a connecting point A. By doing like this, the characteristic of a switch is not excessively affected with the crosstalk in a clock line. By this way, the reliability of the memory circuit as a whole is extremely improved and further the cost is remarkably reduced.
