Abstract
A memory device is provided including a cell array and a volatile storage device. The cell array may include a plurality of word lines, a plurality of bit lines, wherein a selection of a word line and bit line defines a memory cell address, and a non-volatile reserved word line for storing configuration information for the cell array. The volatile storage device is coupled to the cell array. The configuration information from the non-volatile reserved word line is copied to the volatile storage device upon power-up or initialization of the memory device.
Claims37
A memory device, comprising:
- a cell array including
- a plurality of word lines,
- a plurality of bit lines, wherein a selection of a word line and bit line defines a memory cell address, and
- a non-volatile reserved word line for storing configuration information for the cell array;
- and
- a volatile storage device coupled to the cell array, wherein the configuration information from the non-volatile reserved word line is copied to the volatile storage device upon power-up or initialization of the memory device.
A method for storing configuration information for a memory cell array within a reserved sector of the memory cell array, comprising:
- forming a cell array including
- a plurality of word lines,
- a plurality of bit lines, wherein a selection of a word line and bit line defines a memory cell address, and
- a non-volatile reserved word line;
- storing configuration information for the cell array in the non-volatile reserved word line;
- and
- forming a volatile storage device coupled to the cell array.
A memory device, comprising:
- a cell array including
- a plurality of word lines,
- a plurality of bit lines, wherein a selection of a word line and bit line defines a memory cell address, and
- a non-volatile reserved word line containing configuration information for the cell array;
- a volatile storage device coupled to the cell array;
- and
- a control circuit coupled to the cell array, the control circuit adapted to
- read the configuration information from the non-volatile reserved word line upon a power up event or a transfer command,
- store the configuration information in the volatile storage device,
- use the configuration information to configure access to the cell array.
A method for using configuration information for a memory cell array within reserved sector of the memory cell array, comprising:
- reading a configuration information from a non-volatile reserved word line within the memory cell array upon a power up event or a transfer command;
- storing the configuration information in a volatile storage device;
- and
- using the configuration information to configure access to the memory cell array.
A memory device, comprising:
- means for reading a configuration information from a non-volatile reserved word line within the memory cell array upon a power up event or a transfer command;
- means for storing the configuration information in a volatile storage device;
- and
- means for using the configuration information to configure access to the memory cell array.
A machine-readable storage medium comprising instructions for operating a memory device, which when executed by one or more processors causes the one or more processors to:
- read a configuration information from a non-volatile reserved word line within the memory cell array upon a power up event or a transfer command;
- store the configuration information in a volatile storage device;
- and
- use the configuration information to configure access to the memory cell array.
