Patent ID: 8631252

Claim:
An integrated circuit (IC) card of comprising: a central processing unit (CPU); a first memory block having first bit lines and a second memory block having second bit lines, each one of the first and second memory blocks being configured to operate under the control of the CPU; and a high voltage generator block configured to generate a high voltage applied to the first and second memory blocks, wherein once the first bit lines are set up during a first program operation directed to the first memory block with the high voltage, the CPU controls the high voltage generator block to supply the second bit lines with the high voltage during a second program operation directed to the second memory block and running in parallel with the first program operation, the first memory block comprises a first unit control configured to generate a first program complete interrupt upon completion of the first program operation, the second memory block comprises a second unit control configured to generate a second program complete interrupt upon completion of the second program operation, and the CPU is responsive to the first program complete interrupt to load next first program data to the first memory block and the second program complete interrupt to load next second program data to the second memory block.
