Abstract
A random access memory circuit enabling a decodable sense amplifier array for power saving with column steering redundancy. A first decoder receives an input address and accesses at least one memory cell in the array and is capable of executing column steering redundancy. A master redundancy signal is triggered when column steering redundancy is requested. A plurality of sense amplifiers, wherein, each sense amplifier in the plurality of sense amplifiers is coupled to at least one memory cell in an array of memory cells. A second decoder receives the input address and selectively activates a first set of sense amplifiers of the plurality of sense amplifiers and selectively activates a second set of sense amplifiers in the plurality of amplifier only when the master redundancy signal is activated.
