A dual word enable method for memory data access includes the steps of: (i) providing a plurality of address data signals for addressing data stored in an array; (ii) issuing a first row access strobe (RAS) signal to decode the addressing data; and (iii) issuing a second row access strobe (RE2) signal for driving the address data into the memory array after determining that data is present in the memory array.

Dual word enable method and apparatus for memory arrays

The preferred embodiment of the present invention provides a memory system for use in a computer system that improves the performance of a bit redundancy steering mechanism. The preferred embodiment provides a timing signal path to the bit steering mechanism with a delay shorter than that to the memory data array. Additionally, the required address signals are provided to the bit steering mechanism before the addresses are provided to the memory data array. This is preferably accomplished by bypassing the buffers and providing the address signals directly to the bit steering mechanism.
