Abstract
The disclosure is a main row decoder of a semiconductor memory device including: a bank controller for generating an internal RAS signal in response to an active and precharge signal; a first pulse generator for generating a first pulse signal when the internal RAS signal transitions; a second pulse generator for generating a second pulse signal when the internal RAS signal or a self refresh signal transitions; an address latch circuit for latching the least significant bit of a row address in response to the first pulse signal; and a row pre-decoder for decoding outputs of the address latch circuit in response to the second pulse signal.
