Description
Technical Field
The invention relates to the technical field of data storage, in particular to electronic equipment, a power supply method and storage equipment.
Background
A Solid State Drive (SSD) refers to a hard disk manufactured by using a Solid State electronic Memory chip array, and the SSD is composed of a control unit and a storage unit, where the storage unit is, for example, a flash Memory (flash) chip, a Dynamic Random Access Memory (DRAM), and the like, and the SSD is completely the same as a common hard disk in terms of specification, definition, function, and using method of an interface, and has been widely applied to the fields of military, vehicle-mounted, industrial control, video monitoring, network terminal, electric power, medical treatment, aviation, navigation equipment, and the like.
Compared with a traditional Hard Disk Drive (HDD), the SSD has higher reading and writing speed, and simultaneously has excellent shock resistance and falling resistance; however, the SSD uses an electronic medium, that is, a flash memory (NAND flash), and the storage medium is a Single-Level Cell (SLC), a Multi-Level Cell (MLC), or a Three-Level Cell (TLC) and uses charges, which causes the SSD to have a problem of flash data retention (NAND data retention), that is, the SSD has a long-time non-power-on condition, the storage life of data provided by a supplier is generally 1 year, the storage life of data provided by the SSD manufacturer is generally only 3 months, that is, if the SSD storing data is in a power-off state within 1 year, the data in the SSD may be lost.
Specifically, flash memories rely on a series of floating-gate transistors (cells) to store data; the floating gate transistor adopts three-terminal devices as memory cells, namely a source (source), a drain (drain) and a floating-gate (float-gate). The process of writing data into the data unit is the process of injecting charges into a charge potential well, and the data writing process has two technologies, namely hot electron injection (hot electron injection) and F-N tunneling (Fowler Nordheim tunneling), wherein the former is to charge a floating gate (namely a floating gate) through a source, and the latter is to charge the floating gate through a silicon-based layer; the NOR type flash charges the floating gate in a hot electron injection mode, and the NAND charges the floating gate through an F-N tunneling effect; before writing new data, the original data must be erased, which is different from the HDD hard disk, that is, the charges of the floating gates are discharged, and both the two types of flash are discharged through the F-N tunnel effect. Injecting charge into the floating gate indicates that a '0' is written and not injecting charge indicates a '1', so erasing data for flash is writing a 1, as opposed to an HDD. The following describes the Read (Read), write (Program), erase (Erased) operation of a single cell, using SLC as an example:
1) and (3) reading: for the unit with charges in the floating gate, a positively charged space charge region is formed between the source electrode and the drain electrode due to the induction action of the floating gate, and the transistor is in a conducting state no matter whether bias voltage is applied to the control gate; for a transistor without charges in the floating gate, the source and drain can be turned on only when a proper bias voltage is applied to the control gate to induce charges in the silicon-based layer, i.e., the transistor is turned off when no bias voltage is applied to the control gate; as shown in fig. 1. If the source of the transistor is grounded and the drain is connected with the bit line, under the condition of no bias voltage, the data in the memory cell can be obtained by detecting the conducting state of the transistor, if the bit line (bit) is at low level, the transistor is in the conducting state, the read data is 0, and if the bit line is at high level, the transistor is in the cut-off state, and the read data is 1. Since the control gate applies little or no voltage during reading data, which is not enough to change the amount of charge originally in the floating gate, the read operation does not change the original data in the flash.
2) And (3) writing: the NAND Flash can only write erased cells. After the erase operation is completed, there are no electrons in the Cell, and a forward voltage is applied to the Word line (Word line) and the bit line, and the electrons flow from the source to the base. For NOR type Flash, a portion of the high energy electrons enter the floating gate through the insulating layer by hot-electron injection (hot-electron injection); for NAND-type Flash, electrons enter the floating gate by tunneling (tunnel injection); as shown in fig. 2. The two types of flash have the same storage units, the working principle is the same, in order to shorten the access time, the access operation is not carried out on each unit independently, but a certain number of access units are operated collectively, the storage units of the NAND type flash are connected in series, and the units of the NOR type flash are connected in parallel; in order to effectively manage all the memory cells, the memory cells must be uniformly addressed.
3) And (3) erasing operation: in order to erase data in a cell, the erase is performed by pulling out electrons in the floating gate, as shown in fig. 3; the NOR type flash adopts each memory cell to be connected to a bit line in parallel, as shown in figure 4, the parallel connection facilitates random access of each bit, and the NOR type flash has a special address line, so that one-time direct addressing can be realized, and the execution time of the flash to processor instructions is shortened; NAND-type flash memory cells are each connected in series to a bit line for bulk addressing, as shown in fig. 5.
Due to the principle of using the electronic floating gate, the SSD records data by storing charges has a fatal problem that electrons gradually lose with the lapse of time, and when the electrons lose to a certain extent, the level cannot be determined, thereby causing data loss.
In order to solve the above problems, in order to ensure that data stored in the SSD is not lost, the existing solution requires that a user using the SSD to store data needs to ensure that the SSD is powered on at least once every specified time (e.g. half a year), that is, before the electrons are lost to a certain extent, the SSD is powered on once to recover all charges basically; however, this increases the complexity of the operation of the user using the SSD, and meanwhile, if the user fails to power on the SSD in time, the data of the user is lost, so the complexity of the operation of the user using the SSD is increased, and the data security cannot be guaranteed.
