Abstract
Various implementations described herein refer to an integrated circuit having a row of bitcells that are chained together in series to operate as a ring oscillator. Each bitcell in the row of bitcells has multiple transistors that are independent of additional transistors to form the ring oscillator. The multiple transistors of each bitcell in the row of bitcells are arranged to function as an inverter.
