发明名称 Semiconductor memory circuit
摘要 A semiconductor memory circuit, comprising memory cells; word lines, hold lines and bit lines connected to respective memory cells; and a hold-current controlling circuit. The hold-current controlling circuit comprises identical controlling circuit elements connected to respective hold lines and a constant-current source commonly connected to the controlling circuit elements. Each of the controlling circuit elements comprises means for absorbing electric charges from respective hold lines, when corresponding word lines change from a selection status to a non-selection status, until the voltage level of the hold line reaches a full "L" or "H" level, and means for blocking a flow of electric charges from the hold line, when a corresponding word line changes from a non-selection status to a selection status, during a predetermined interval after time data switching from one memory cell to another memory cell is performed.
