Abstract
The memory device includes a die with a plurality of memory blocks which are physically arranged in six planes. The die is configured to allow parallel operations in memory blocks of any combination of all six plane. The memory device also includes circuitry that is configured to operate the die in at least two different operating modes depending on a type of memory product that the die is connected with. The at least two operating modes include a four-plane operating mode, wherein memory blocks in only four of the six planes can be selected simultaneously, and a six-plane operating mode, wherein memory blocks in all six planes can be selected simultaneously.
Claims20
A method of performing an operation in a memory device, comprising the steps of:
- preparing a die that includes a plurality of memory blocks which are physically arranged in six planes, the die being configured to allow parallel operations in memory blocks of any combination of all six planes;
- and
- configuring the die to operate in at least two different operating modes depending on a type of memory product that the die is electrically connected with, the at least two operating modes including a four-plane operating mode wherein memory blocks in only four of the six planes can be selected simultaneously and a six-plane operating mode wherein memory blocks in all six planes can be selected simultaneously.
A memory device, comprising:
- a die that includes a plurality of memory blocks which are physically arranged in six planes, the die being configured to allow parallel operations in memory blocks of any combination of all six planes;
- and
- circuitry that is configured to operate the die in at least two different operating modes depending on a type of memory product that the die is connected with, the at least two operating modes including a four-plane operating mode wherein memory blocks in only four of the six planes can be selected simultaneously and a six-plane operating mode wherein memory blocks in all six planes can be selected simultaneously.
An apparatus, comprising:
- a memory product including at least one die;
- the at least one die including a plurality of memory blocks which are physically arranged in six planes, the at least one die being configured to allow parallel operations in memory blocks of any combination of all six planes;
- and
- a controlling means that is configured to determining if the memory product is of a first type that is not able to perform six parallel operations or is of a second type that is able to perform six parallel operations;
- the controlling means being further configured to organize the memory blocks into groups of four memory blocks per group in response to a determination that the memory product is of the first type and to organize the memory blocks into groups of six memory blocks per group in response to a determination that the memory product is of the second type.
