1. A memory array comprising:
a first set of one-time programmable (OTP) cells including:
a first subset of OTP cells extending and connected between a first program control line and a first read control line, wherein each OTP cell of the first subset of OTP cells includes a programmable storage device and a switch extending and connected between the first program control line and the first read control line, wherein the first program control line extends towards a first side of the memory array along a first direction, wherein the first read control line extends towards a second side of the memory array facing away from the first side of the memory array,
wherein the first set of OTP cells further includes:
a second subset of OTP cells extending and connected between a second program control line and a second read control line, wherein each OTP cell of the second subset of OTP cells includes a programmable storage device and a switch extending and connected between the second program control line and the second read control line, wherein the second program control line extends towards the first side of the memory array along the first direction, wherein the second read control line extends towards the second side of the memory array, wherein the first program control line and the second program control line are coupled to a global program control line extending along a second direction traversing the first direction, and wherein the first read control line and the second read control line extend along the first direction and are coupled to a global read control line extending along the second direction.
