Method and device for updating a program

A method for updating a program in a memory, the memory including a plurality of blocks, the method comprising:

• executing a first image of the program while an address space of the program is imaged onto the blocks and the blocks are operated in a single level mode;
• processing a second image of the program by executing a plurality of iterations of a series of steps, wherein the iterations are executed until an entirety of the second image is processed and the steps of the iterations include:
• copying a part of the first image, which was formed from the imaging of an address range within the address space onto one of the blocks, to a backup block of the memory;
• setting the one of the blocks to a multi-level mode;
• while the one of the blocks is set to the multi-level mode and the address range is temporarily imaged onto the backup block, programming the one of the blocks with a respective part of the second image;
• and
• switching the address range back to the one of the blocks while the one of the blocks remains in the multi-level mode;
• and
• subsequent to the execution of the iterations of the processing of the entirety of the second image, executing the second image in place of the first image.

A non-transitory computer-readable medium on which are stored instructions that are executable by a processor and that, when executed by the processor, causes the processor to perform a method for updating a program in a memory, the memory including a plurality of blocks, the method comprising:

• executing a first image of the program while an address space of the program is imaged onto the blocks and the blocks are operated in a single level mode;
• processing a second image of the program by executing a plurality of iterations of a series of steps, wherein the iterations are executed until an entirety of the second image is processed and the steps of the iterations include:
• copying a part of the first image, which was formed from the imaging of an address range within the address space onto one of the blocks, to a backup block of the memory;
• setting the one of the blocks to a multi-level mode;
• while the one of the blocks is set to the multi-level mode and the address range is temporarily imaged onto the backup block, programming the one of the blocks with a respective part of the second image;
• and
• switching the address range back to the one of the blocks while the one of the blocks remains in the multi-level mode;
• and
• subsequent to the execution of the iterations of the processing of the entirety of the second image, executing the second image in place of the first image.

A device comprising a processor, wherein the processor is configured to perform a method for updating a program in a memory, the memory including a plurality of blocks, the method comprising:

• executing a first image of the program while an address space of the program is imaged onto the blocks and the blocks are operated in a single level mode;
• processing a second image of the program by executing a plurality of iterations of a series of steps, wherein the iterations are executed until an entirety of the second image is processed and the steps of the iterations include:
