Abstract
An integrated circuit memory device includes a main row decoder, a sub-row decoder, and a sub-word line driver. The main row decoder decodes the first portion of a row address, and generates a main row activation signal when one of the plurality of rows have been selected. The sub-row decoder decodes a second portion of the row address, and generates a first sub-row activation signal when a first one of the plurality of rows has been selected. The sub-row decoder generates a second sub-row activation signal when a second one of the plurality of rows has been selected. The sub-word line driver activates a first memory cell in the first row in response to the main row activation signal and the first sub-row activation signal. The sub-word line driver activates a second memory cell of the second row in response to the main row activation signal and the second sub-row activation signal. The sub-word line driver includes a first driver circuit which activates the first memory cell in response to the main row activation signal, the first sub-row activation signal, and an inverse of the first sub-row activation signal. The sub-word line driver also includes a second driver circuit which activates a second memory cell in response to the main row activation signal, the second sub-row activation signal, and an inverse of the second sub-row activation signal.
