Relative ground selection signal generator and relative ground selection circuit

摘要

The present invention relates to a circuit for selecting a bit line and a relative ground line, and more particularly to a circuit for selecting a relative ground line necessary for a circuit structure of a parallel type (NOR type) Conventionally, a signal generating circuit is required for each of the (N + 1)-th relative ground selection signal and the N-th bit line selection signal, and by selecting the respective relative grounds for the left and right selection transistors, However, the present invention is not limited to the case where the address for the relative ground selection is added to the address data, and the N-th A relative ground selection signal and an N-th bit line selection signal at the same time, In addition, by using the common ground relative to the left and right selection transistors, the number of transistors is minimized, thereby reducing the chip size, increasing the space holding ratio inside the chip, and solving the time delay factor due to the convenience of the process and the use of more transistors than necessary.
