Abstract
The present data storage system employs a memory controller with embedded logic to selectively XOR incoming data with data written in the memory to generate XOR parity data. The memory controller automatically performs XOR operations on incoming data based upon the address range associated with the memory 'write' request. The system provides data migration and parity generation in a simple and effective manner and attains reduction in cost and power consumption. The memory controller may be built on the basis of FPGAs, thus providing an economical and miniature system.
