READ/WRITE SYSTEM AND CIRCUIT FOR SEMICONDUCTOR MEMORIES

摘要

This disclosure relates to a system and semiconductor circuit for reading out of and writing into selected storage cells of a semiconductor memory. In particular, the disclosure relates to such a system and circuit wherein a group of cells utilizes a single decoder for both the read and write operations. The use of a single decoder for a group of cells is accomplished by utilizing both the in-phase and out-of-phase outputs of each decoder to minimize the number of logic stages required.
