Abstract
A delayed bitline leakage compensation circuit for memory devices is disclosed. The delayed bitline leakage compensation circuit includes a bitline leakage model circuit for modeling discharge of a bitline by leakage current in a read operation. It further has a delayed charge signal generator for generating a delayed charge signal in response to the bitline leakage model circuit discharging to approximately a discharge threshold. The delayed charge signal generator is deactivated if the bitline is discharged by a selected memory cell. Moreover, the delayed bitline leakage compensation circuit includes a delayed charge circuit for charging the bitline in response to the delayed charge signal.
