Abstract
A semiconductor chip comprises a word line configured to be driven by a word line driver. The semiconductor chip also comprises a plurality of bit lines. Each bit line of the plurality of bit lines is configured to transmit a signal to a respective bit line amplifier. The semiconductor device further comprises a plurality of memory cells. At least one memory cell of the plurality of memory cells is at an intersection of the word line and a bit line of the plurality of bit lines. The at least one memory cell of the plurality of memory cells is a type selected from at least two memory cell types based on a distance of the intersection from an end of the word line.
