Features
Global Wear Leveling – Advanced algorithms to enhance wear-leveling efficiency
Global wear leveling ensures every block has an even erase count. By ensuring all spare blocks in the SSD’s flash chips
are managed in a single pool, each block can then have an even erase count. This helps to extend the lifespan of a SSD
and to provide the best possible endurance.
There are three main processes in global wear -leveling:
(1) Record the block erase count and save this in the wear-leveling table.
(2) Finds the static-block and saves this in the wear-leveling pointer.
(3) Checks the erase count when a block is pulled from the pool of spare blocks. If the erased block count is larger
than the Wear Count (WEARCNT), then the static blocks are leveraged against the over-count blocks.
ECC Algorithm
The controller uses a BCH 42 Bit ECC algorithm per 1024 bytes depending on the structure of the flash. BCH42 may
correct up to 42 random bit errors within 1024 data bytes. With the help of BCH42 ECC, the endurance of the
Transcend SSD is greatly improved.
Bad Block Management
When the flash encounters an ECC, program or erase failure, the controller will mark the block as a bad block to
prevent use of this block and cause data loss in the future.
Advanced Garbage Collection
Transcend’s Garbage Collection mechanism improves SSD performance. Advanced Garbage Collection can efficiently
improve memory management to ensure stable SSD performance. Transcend’s advanced flash management can
maintain the drive’s high performance even after an extended operating time.
Enhanced S.M.A.R.T. function
Transcend’s SSDs support the innovative S.M.A.R.T. command (Self-Monitoring, Analysis, and Reporting Technology)
which allows users to evaluate the health status of their SSD efficiently.
Hardware Purge and Hardware Write Protect (Optional)
The SSDs have optional features such as hardware trigger for quick data erase and write protection. These features
may be enabled by simply connecting a switch to the designated pins.
StaticDataRefresh Technology
Normally, the ECC engine corrections take place without affecting normal host operations. Over time, the number of
bit errors accumulated in the read transaction exceeds the correcting capacity of the ECC engine, which results in
corrupted data being sent to the host. To prevent this, the controller monitors the bit error levels during each read
operation; when the number of bit errors reaches the preset threshold value, the controller automatically performs a
data refresh to “restore” the correct charge levels in the cell. Implementation of StaticDataRefresh Technology
reinstates the data to its original, error-free state, and hence, lengths the data’s lifespan.
