Filed: 1995-02-06
Abstract: PURPOSE: To reduce peak current by an arrangement wherein multiple row decoder groups can be operated while being divided by the output signals from multiple relays being controlled by a block select address signal. CONSTITUTION: When output signals Axi , Axi from a row address buffer 1 are inputted, in High state, to the NAND gate G5 of a row predecoder 2, an output signal passed through inverters G6, G7 goes Low before being inputted to first through N-th repeaters R1-RN.
