Abstract
In a ROM structure, power consumption is reduced by providing for pre-discharging of only the bit line corresponding to the memory location that is being read. Column select lines are coupled to logic to switch in a pre-discharging circuit prior to reading, and to disconnect, from the pre-discharging circuit during reading, only the bit line corresponding to the memory location being read.
