Abstract
A method of controlling a memory device includes receiving an address value that indicates a range of addresses within the memory device, each address within the range of addresses corresponding to storage locations within each of two distinct storage dice within the memory device. The address value is stored within a programmable register within the memory device.
Claims20
A method of controlling a memory device, the method comprising:
- receiving an address value that indicates a range of addresses within the memory device, each address within the range of addresses corresponding to storage locations within each of two distinct storage dice within the memory device;
- storing the address value within a programmable register within the memory device.
A memory device comprising:
- a non-volatile storage die including first storage locations;
- a volatile storage die including second storage locations;
- and
- a programmable register coupled to the non-volatile storage die and the volatile storage die and operable to store an address value that specifies a range of addresses in which each address corresponds to a shadowed address having overlapping storage locations within the first storage locations and the second storage locations.

A memory comprising:
- a first storage die including first shadowed storage locations;
- a second storage die distinct from the first storage die and including second shadowed storage locations;
- a programmable register coupled to the first storage die and the second storage die and operable to store an address value representing a range of addresses corresponding to the first and second shadowed storage locations;
- and
- logic coupled to the first storage die and the second storage die, the logic to access the first and second shadowed storage locations based on whether a received address associated with a write command is within the range of addresses.
