Technical field
The present invention relates to solid state storage technologies fields, are specifically related to a kind of side for reducing rblock capacity in solid state hard disk
Method and its system.
Background technique
The storage of existing solid-state hard disk SSD FTL (Flash Translation Layer, NAND Flash management algorithm)
The capacity that the Managed Solution of block Block will lead to a logic storage unit rblock is increasing, to be based on Micron L95B
2TB SSD for, be made of 128 flash memory die Die altogether, the capacity of each rblock has reached 256 physics plane
The physical capacity of block, 2GB.That means that FTL only in the memory space as this 2GB without any valid data
When, which could being recycled to and the problem of reusing, thus bring be, the speed of block recycling becomes very slow, is not had
There is the rblock recovery efficiency of low capacity high.
For MLC/TLC FLASH, since one minimum memory unit (cell) can store 2~3 bit's
Data, this cell are not completely written before i.e. its 2/3 bit are programmed, this cell is constantly in dangerous shape
State.Once improper power down occurs, it is non-that loss of data possibility occurs for the cell (part bit is programmed) not being completely written to before
Chang Gao.As soon as if that the Die number of composition rblock is excessive, a certain moment is more in the presence of the cell not being completely written to,
When the data for occurring to lose when improper power down accordingly will be more.
With the development of NAND Flash technology, the capacity of single block is also increasing, especially 3D TLC FLASH
The sequence of the appearance of technology, the way to manage of the block of SSD FTL, data write-in also becomes from the write-in of single physical page
Multiple physics page are written simultaneously.The concurrent fashion of original Flash read-write operation is also required to and then change, these are required
Corresponding block Managed Solution is supported.From the point of view of general trend, logic storage unit, that is, rblock capacity is smaller, to reduction
The complexity of 3D TLC FTL design is more helpful.
