Abstract
A static semiconductor memory device comprises memory cells arranged in a matrix having columns and rows, and bit selection circuits provided in the respective columns. Each of the bit selection circuits is adapted to receive a column selection signal, having a high reference potential, when the corresponding column is selected for supplying a current to the selected column. A discharge path is provided in each bit selection circuit so that the potential of the column selection signal is rapidly lowered when the column is switched from a selected state to a nonselected state, whereby the power consumption is lowered and high speed operation is achieved.
