Description
Technical field
The present invention relates to storage device technical field, specially a kind of effective storage mode for recorder.
Background technique
Traditional capsule information are recorded in NOR Flash, until the fast, durability with writing rate occurs in NAND Flash, can
Become the replacer of NOR Flash by advantages such as property, the minimum read/write unit of NAND Flash is one page, and NOR Flash is big
Mostly it is a byte, therefore some images or large capacity data can select to be recorded in NAND Flash, and frequently records key
Few capacity data NOR Flash is more particularly suitable, so memory is usually or one NOR Flash or plug-in one embedded
SPI NOR Flash, when recorder start recording data, crucial a small amount of data is first stored in Nor Flash, waits Nor
Data writes full one page again by the corresponding page of these data write-in Nand Flash, after Nor Flash writes full by data also in Flash
It needs to do erasing move, write-in next time data could be allowed.
Traditional storage mode key data is by flash memory storage, and the read or write speed of flash memory is lower, and power down data meeting
It loses, it would therefore be highly desirable to which a kind of improved technology solves the problems, such as this in the presence of the prior art.
Summary of the invention
The purpose of the present invention is to provide a kind of effective storage mode for recorder, the crucial a small amount of data of traditional record
Flash memory replaced with memory storage (FRAM, MRAM or RRAM), not only have the speed (nanosecond) of RAM, read or write speed ratio
Fast 1000 times of flash memory, and there is non-volatile characteristic power down data not lose, all it is more suitable for the instrument that keeps a record than current any material
Key data frequently store, few capacity data is frequently recorded to storage device very big help, to solve above-mentioned background technique
The problem of middle proposition.
To achieve the above object, the invention provides the following technical scheme: a kind of effective storage mode for recorder, packet
Include following steps:
Step 1: recorder, recorder start recording data are opened；
Step 2: key data is written in memory storage；
Step 3: corresponding positions in Nand-Flash memory are written into one page if data in memory storage writes full one page
It sets, continues to receive data write-in if data in memory storage does not write full one page；
Step 4: step 1 is repeated.
Preferably, data are video data in the step 1.
Preferably, memory storage is nonvolatile memory in the step 2, and the memory storage is
FRAM, MRAM or RRAM it is therein any one；
Wherein, the FRAM realizes that data store using the ferroelectric effect of ferroelectric crystal；
Wherein, the write operation of the MRAM is realized by the magnetization reversal of free layer in magnetic tunnel-junction；
Wherein, the RRAM be according to the difference for applying voltage on an metal oxide, make the resistance of material in high-impedance state and
Corresponding change occurs between low resistance state, thus unlatching or blocks current flow channel, and various information are stored using this property
Memory.
Preferably, the data of Nand-Flash are stored in memory cell in a manner of bit in the step 3,
The NAND-flash reads and writes data as unit of page and wipes data in blocks.
Compared with prior art, the beneficial effects of the present invention are:
The flash memory of the crucial a small amount of data of traditional record is replaced with memory storage (FRAM, MRAM or RRAM), is not only had
The speed (nanosecond) of RAM, read or write speed greatly improves, and has non-volatile characteristic power down data not lose, than as predecessor
What material be all more suitable for keeping a record key data of instrument frequently stores, and frequently record to storage device and lacks capacity data and have very big side
It helps.
Detailed description of the invention
Fig. 1 is the method for the present invention flow diagram.
