Abstract
In one aspect, a non-volatile memory system includes a plurality of memory cell arrays having different read stand-by times. For example, the non-volatile memory system may include a single-level cell (SLC) array composed of a plurality of SLCs, and a multi-level cell (MLC) array composed of a plurality of MLCs. In this case, the SLC array and the MLC array receive a read instruction at the same time and prepare to read data at the same time. However, the SLC array begins to read the data prior to the MLC array, and the MLC array begins to read the data once the SLC array has completely read the data.
Claims17
A non-volatile memory system comprising:
- a single-level cell (SLC) array composed of a plurality of SLCs;
- and
- a multi-level cell (MLC) array composed of a plurality of MLCs,
- wherein the SLC array and the MLC array receive a read instruction at the same time and prepare to read data at the same time.
A non-volatile memory system comprising a plurality of memory cell arrays which receive a read instruction at the same time and have respectively different read stand-by times,
- wherein each memory cell array comprises a plurality of memory cells, and
- wherein a memory cell array having a shortest read stand-by time among the plurality of memory cell arrays firstly begins to read data in response to the read instruction.
A non-volatile memory system comprising:
- a single-level cell (SLC) array composed of a plurality of SLCs;
- and
- a multi-level cell (MLC) array composed of a plurality of MLCs,
- wherein the SLC array and the MLC array share row addresses.
A non-volatile memory system comprising a plurality of memory cell arrays which receive a read instruction at the same time and have respectively different read stand-by times,
- wherein each memory cell comprises a plurality of memory cells, and
- wherein the memory cell arrays share row addresses.
A data read method of a non-volatile memory system comprising a single-level cell (SLC) array composed of a plurality of SLCs and a multi-level cell (MLC) array composed of a plurality of MLCs, the data read method comprising:
- applying a read instruction to the MLC array and the SLC array at the same time;
- the SLC array and the MLC array preparing to read data at the same time;
- and
- the SLC array reading the data.
