Title: Semiconductor memory
Inventor: OONO CHIKAU
IPC: G11C11/414
Filed: 1982-12-28
Abstract: PURPOSE:To omit a current switch and a time constant circuit at each pair of word line and to prevent double selection by connecting a word line discharging resistor to at least one of each pair of word lines and then connecting the other terminal of each resistor to a constant current source. CONSTITUTION:A word line discharging circuit WDC1 consists of a word line discharging resistor Rd, a line L1 and a constant current source CI. The constant current source CI always extracts constant current (i) from the line L1, and especially, extracts the largest quantity of current from a specific resistor out of these resistors Rd. The specific resistor means the resistor Rd having the highest potential out of all the resistors Rd at the other terminal. Namely, the current ird conducting into the resistor Rd inserted into the selected word line is the maximum. In addition, a large amount of current ird is extracted from the resistor Rd inserted into the word line overflowing charge. Thus, the extraction of current suppresses double selection.
