Integrated circuit I/O using a high performance bus interface
First Claim
1. A memory device addressable over a range of addresses, the memory device comprising:
- plurality of independently addressable memory sections, wherein each of the memory sections is assigned a portion of the range of addresses, each of the memory sections comprising an array of memory cells connected in rows and columns; and
a plurality of address registers coupled to the plurality of memory sections, each address register for storing information indicating a portion of the range of addresses that corresponds to one of the plurality of memory sections, and wherein at least one of the plurality of address registers specifies that a zero portion of the range of addresses is assigned to at least one of the plurality of memory sections if the at least one of the plurality of memory sections is defective.

Abstract
The present invention includes a memory device having a plurality of independently addressable memory sections, each of the memory sections is assigned a portion of the range of addresses. A plurality of address registers coupled to the plurality of the memory sections, each address register for storing information indicating a portion of the range of addresses that corresponds to one of the plurality of memory sections. One of the plurality of the address registers specifies that a zero portion of the range of the addresses is assigned to one of the plurality of memory sections if the at least one of the plurality of the memory sections is defective.
