Abstract

A memory bit cell includes a first memory cell including a first antifuse transistor and a first selection transistor, the first antifuse transistor being selectable between a first state or a second state in response to a first signal, the first selection transistor being configured to provide access to the first antifuse transistor in response to a second signal; a second memory cell including a second antifuse transistor and a second selection transistor, the second antifuse transistor being selectable between the first state or the second state in response to the first signal, the second selection transistor being configured to provide access to the second antifuse transistor in response to the second signal; a first word line to selectively provide the first signal; a second word line to selectively provide the second signal; and a bit line for sensing the first state or the second state.
