Abstract
A dynamic random access memory device includes an array of dynamic random access memory cells subdivided into a group of blocks. Each of the blocks of memory cells can be independently operated in either a single cell mode or a twin cell mode.
Claims15
A method of operating a dynamic random access memory (DRAM) device that includes memory cells organized in a plurality of blocks, the method comprising:
- storing data in a first block of memory cells, the data being stored in the first block in a single cell mode;
- and
- storing data in a second block of memory cells, the data being stored in the second block in a twin cell mode, wherein the second block stores data in the twin cell mode at the same time the first block stores data in the twin cell mode.
A method of operating a dynamic random access memory device, the method comprising:
- providing an array of dynamic random access memory cells arranged in a plurality of blocks;
- and
- storing data in ones of the blocks of memory cells, wherein the data is stored in either a single cell mode or a twin cell mode as a function of the block.
A method of operating a digital recording device, the method comprising:
- recording a digital image;
- storing the recorded digital image in a dynamic random access memory, the recorded digital image being stored in a single cell mode;
- processing the recorded digital image;
- and
- storing the processed digital image in the dynamic random access memory, the processed digital image being stored in a twin cell mode.
