Abstract
A memory module using a plurality of partially defective RDRAM devices in combination to simulate a single, fully operational RDRAM device. Multiple, partially defective RDRAM devices are configured to simulate a fully operational RDRAM device by taking advantage of the manner in which defective cells are localized on each RDRAM device.
Claims18
A memory module comprising at least two partially defective RDRAM devices, each having at least partially complementary defects, wherein the at least two partially defective RDRAM devices, in combination, comprise a fully functional RDRAM.
A computer memory system comprising:
- a memory controller;
- and
- at least two partially defective RDRAM devices, each having at least partially complementary defects, wherein the at least two partially defective RDRAM devices, in combination, comprise a fully functional RDRAM.
A computer system comprising:
- a processor;
- at least one input device coupled to the processor and adapted to allow data to be input to the processor;
- at least one output device coupled to the processor and adapted to allow the processor to output data;
- at least one storage device coupled to the processor adapted to store information for use by the processor;
- and
- a memory device coupled to the processor for storing data and instructions for use by the processor, the memory device comprising:
- a memory module comprising at least two partially defective RDRAM devices, each having at least partially complementary defects, wherein the at least two partially defective RDRAM devices, in combination, comprise a fully functional RDRAM.
