Abstract

A non-volatile storage device storing a data bit received from a bitline via an accessing circuit. A coupling circuit couples either the bitline, or a complementary bitline to a biasing circuit dependent on the logic level of the data bit stored in the storage device. The biasing circuit generates a match signal when a data bit having the same logic level as the stored data bit is applied to the bitline.
