An OTP memory array includes a bit line coupled to a plurality of memory banks. Each memory bank includes a plurality of memory cells, a footer, and a bias device, and is associated with a current mirror. When a memory cell is activated (e.g., for reading) the memory bank including the activated memory cell is referred to as an activated memory bank and other banks are referred to as deactivated memory banks. A current tracking device serves to compensate for bit line leakage current in deactivated memory cells in the activated memory bank. Further, footers and bias devices in deactivated memory banks and associated current mirrors are configured to reduce/eliminate bit line current leakage through deactivated memory cells in deactivated memory banks.
