Abstract:
A processor including a memory and a control module. The memory has an array of cells. The control module is configured to: determine a number of access cycles along a first word line; determine an extended period based on the number of the access cycles; generate a word line signal to maintain the first word line in an activated state during (i) an initial period and (ii) the extended period; and access a first cell during the extended period. The first cell is connected to the first word line. The control module is further configured to deactivate the word line and maintain the first word line in a deactivated state while accessing a second cell connected to the first word line. The accessing of the second cell is based on a bit line separation provided during the extended period.
