5. Block Diagram and Function Explanations 5.1 Block Diagram 5.2 Function Explanations 5.2.1 Global Wear Leveling Function Global wear leveling ensures that every block has an even erase count. This helps to extend the life expectancy of an SSD. There are three main processes in global wear leveling: (1) Record the block erase count and save this in the wear-leveling table. (2) Find the static-block and save this in the wear-leveling pointer.
of the ECC engine, resulting in corrupted data being sent to the host. In order to prevent such occurrence, the controller monitors the error bit levels at each read operation; when it reaches the preset threshold value, the controller automatically performs data refresh to “restore” the correct charge levels in the cell. This implementation practically restores the data to its original, error-free state, and hence lengthening data life. 5.2.
The device manager may create a logical block address (LBA) range and assign different permissions for each LBA range. Only users with the correct key for a particular LBA range may perform permitted actions. Where drive locations are password-protected, only users with the correct key will be authorized entry. 5.2.8 RAID engine RAID engine technology stores data parity information in a specific area. The parity information can restore damaged data back which can enhance data reliability. 5.2.
6 Technology Term Explanations 6.1 TBW Terabytes Written (TBW) directly measures how much you can write cumulatively into the drive over its lifetime. Essentially, it just includes the multiplication conducted above in the measurement itself. For example, if your drive is rated for 365 TBW, that means you can write 365 TB into it before a replacement is required. If its warranty period is 5 years, that works out to 365 TB ÷ (5 years × 365 days/year) = 200 GB of writes per day.
7 Installation Requirements 7.1 Card Insertion Angles insertion is allowable and preferred; the intention is to minimize the insertion/extraction force. Minimum of angle of insertion is 5° Minimum two step insertion is desirable; the intention is to minimize the insertion/extraction force.
8 Command Descriptions 8.1 Support Admin Command Register The Admin command set is the commands that are submitted to the Admin Submission Queues. The detailed specifications are described in NVM Express specification document.
8.2 SMART / Health Log Page [Table 18] SMART Data information BYTE Description Default Value Critical Warning 0 Bits Description 07:05 Reserved 04 If set to‘1’, then the volatile memory backup device has failed. This field is only valid if the controller has a volatile memory backup solution. 03 If set to‘1’, then the media has been placed in read only mode.
