Bypass Circuitry for Memory Applications
Various implementations described herein are directed to an integrated circuit having core circuitry with an array of bitcells arranged in columns of bitcells that may represent bits. A first column of bitcells may represent a nearest bit of the bits, and a last column of bitcells may represent a farthest bit of the bits.
