Abstract
A memory device includes a flag register to modify the address map of the memory device based on the state of an input node on the memory device.
Claims20
A memory device comprising:
- a plurality of memory blocks;
- a plurality of programmable flags, wherein each of the memory blocks is associated with a corresponding one of the plurality of programmable flags;
- and
- a control circuit to gate access to each of the plurality of memory blocks based on a state of the corresponding programmable flag and a state of an input to the memory device.
1 more element
An integrated circuit comprising a memory device having a plurality of blocks conditionally visible in an address space based on a logical state of an input node and based on flag values programmed in the memory device, wherein each of the flag values corresponds to one of the plurality of blocks.
A method comprising:
- receiving values for programmable flags within a memory device to assign memory blocks to one of two privilege modes;
- providing a first address map when the memory device is accessed when an external node on the memory device is set to a first of the two privilege modes;
- and
- providing a second address map when the memory device is accessed when the external node on the memory device is set to a second of the two privilege modes.
1 more element
A system comprising:
- an antenna;
- a receiver coupled to the antenna;
- a processor coupled to the receiver;
- and
- a memory device coupled to the processor, the memory device comprising a plurality of memory blocks, a plurality of programmable flags, wherein each of the memory blocks is associated with a corresponding one of the plurality of programmable flags, and a control circuit to gate access to each of the plurality of memory blocks based on a state of the corresponding programmable flag and a state of an input to the memory device.
