Abstract
In one embodiment, a solid state device includes a controller and a non-volatile memory. The non-volatile memory includes a plurality of dies. Each die includes a plurality of planes. A first super-plane-block is structured from a first plane of the plurality of dies. A second super-plane-block is structured from a second plane of the plurality of dies. A plurality of memory operation instructions that, when executed by the controller, cause the controller to receive a first data stream, write the first data stream to the first super-plane-block, receive a second data stream, and write the second data stream to the second super-plane-block.

A solid state device, comprising:
- a non-volatile memory comprising a plurality of dies having multiple planes;
- and
- a controller coupled to the non-volatile memory configured to:
- structure the non-volatile memory into a plurality of super-plane-blocks, each super-plane-block spanning separate planes of the plurality of dies;

- write a first data stream to the first super-plane-block;
- write a second data stream to the second super-plane-block;
- write a parity information of the first data stream on the first plane of the multiple planes of the XOR die;
- write a parity information of the second data stream on the second plane of the multiple planes of the XOR die;

A solid state device, comprising:
- a controller;
- a data stream support means for simultaneously writing separate data from two separate data streams on NAND flash memory;
- and
- a plurality of memory operation instructions that, when executed by the controller, cause the controller to simultaneous write separate data to the data stream support means wherein invalidation of the separate data of one of the two separate data streams causes erasure of the separate data of the one of the two separate data streams without garbage collection of the separate data of another of the two separate data streams.
