Abstract:
A memory device includes a non-volatile memory chip, a connector and a memory controller. The non-volatile memory chip includes an access partition and a hidden partition. The memory controller is used to set first logical blocks mapping to mapping physical blocks in the access partition. The memory controller is used to maintain a first mapping table recording the first logical blocks and the mapping physical blocks. During backup, the memory controller is used to duplicate data in the mapping physical blocks to the hidden partition according to the first mapping table to form backup physical blocks, and establish a second mapping table setting second logical blocks to map to the backup physical blocks. During recovery, the memory controller is used to map the second logical blocks to the backup physical blocks according to the second mapping table for the host system to recover an environment set at the backup operation.
Abstract:
A data storage system with information security protection includes an SSD and at least one activation device selectively connected to the SSD. The SSD has a device identifier, and includes a data storage unit and a controlling and processing unit. The controlling and processing unit is in information connection with the data storage unit, and is written with at least one set of firmware data that is triggered and activated by an activation key to execute a predetermined task on the data storage unit. The activation device includes a data processing unit which is written with the activation key in advance, and has a pairing mode and an enabling mode. In the pairing mode, the data processing unit accesses and stores the device identifier. In the enabling mode, the data processing unit compares the stored device identifier to output the activation key to the controlling and processing unit.

The detecting method detects whether an output signal from a host is received by Pin 41, Pin 43, Pin 47 and Pin 49 of the connector, or Pin 29, Pin 31, Pin 35 and Pin 37 of the connector, or Pin 17, Pin 19, Pin 23 and Pin 25 of the connector, or Pin 5, Pin 7, 11 and Pin 13 of the connector. According to the detecting result and the output signal, the electronic card judges the communication protocol of the host is a SATA communication protocol, a PCIe communication protocol or a USB3.0 communication protocol.
Abstract:
A writing management method and a writing management system for a solid state drive are provided. The writing management method includes the following steps. Firstly, plural write commands are transmitted to a firmware so as to write at least one data to the solid state drive, wherein each of the plural write commands contains a logical block address and a sector count. Then, the logical block addresses and the sector counts of the plural write commands are sequentially stored to the firmware. Then, an application program sequentially reads the logical block addresses and the sector counts. Then, a sequential write ratio is determined according to the logical block addresses and the sector counts. Afterwards, the application program updates the firmware to a first firmware according to the sequential write ratio.
Abstract:
A storage device is connected with a host. The storage device includes a control module, a first storage module and a second storage module. The first storage module having a first storage region and a second storage region is connected with the control module. The second storage module is connected with the control module. To-be-accessed data are stored and read in the first storage region or the second storage region of the first storage module by the control module. The to-be-accessed data stored and read in the first storage region are correspondingly stored and read in the second storage module by the control module, so that the second storage region is exclusively used for temporary storage of data, the storage modules are effectively utilized, and the lifetime decrease of the storage device is avoided.
Abstract:
An oculink electronic device having a flexible circuit board includes an oculink connector, a first rigid circuit board, a second rigid circuit board and the flexible circuit board. The first rigid circuit board is connected with the oculink connector. The flexible circuit board is extended from the first rigid circuit board and the second rigid circuit board and disposed between the first rigid circuit board and the second rigid circuit board. Therefore, not only the assembling steps are reduced, but also the total length is significantly shortened. The rotatable characteristic is provided, and the space requirement of installation is reduced.
Abstract:
The present disclosure illustrates a method of extending a lifetime of a solid state disk (SSD). The SSD includes a flash memory which is a multi-level cell (MLC) flash memory. The method includes steps of: setting a number of logic blocks of the SSD to be one-half of a number of physical blocks of the flash memory; reading, by a control unit of the SSD, a write/erase times of each of the physical blocks of the flash memory; and converting the physical block, of which a number of the write/erase times exceeds an upper limit of the write/erase times, from a multi-level storage format to a single-level storage format. A number of the logic blocks is a constant value.
Abstract:
A logic block addressing (LBA) configuration method and a non-volatile memory device having the same are provided. The non-volatile memory device determines one of logic zones configured in an LBA table according to the number of booting times. The selected logic zone corresponds to a data zone configured in a physical volume. The non-volatile memory device accesses data stored in the data zone in the selected logic zone. Accordingly, in each boot, the instant disclosure provides the LBA configuration method and the non-volatile memory device having the same, which can show data stored in the different data zones of the physical volume to simplify user operation and avoid the user maliciously destroying or erroneously deleting other data stored in the unused data zones of the physical volume, thereby enhancing the efficiency of the non-volatile memory device executing the multi-booting.
