Introduction: Single-level cell (SLC) and multi-level cell (MLC) Flash memory are similar in their design. MLC Flash devices cost less and allow for higher storage density. SLC Flash devices provide faster write performance and greater reliability, even at temperatures above the operating range of MLC flash devices. Multi-level cell (MLC) solid state disks (SSDs) strike the right balance for cost, number of read/write cycles, and read/write speed in most embedded system applications. TLC (like MLC) increases the number of bits per cell. For MLC, you store two bits per cell, which means instead ..read more

Secure Erase initiates a block-by-block, data pattern write operation to systematically erase any trace of the user data on SSD drivers. Secure erase is essentially a series of data deletion commands that provide “electronic data shredding” capability for flash products. In a regular SSD, deleting a file only removes its name from the directory or file table. User data remains until overwrite by new data. Even reformatting the SSD leaves data intact. Mainkco Military Secure Erase SSD can overwrite or destroy all User data in all allocated blocks and file tables, as well as data in reallocated ..read more

Product reliability is the key element in its industrial applications while product quality and reliable improvements the focus of every manufacturer. SSD “write protection” technology is designed to protect data integrity. This write protection function is enabled by hardware or software settings. When SSD firmware finds that the function is enabled, it continues to accept the write-in command from the host without writing data into NAND Flash. That is, it maintains the integrity of data in SSD by setting disks into read-only and disabling the write-in command by the host. another write pro ..read more

Background: Sensitive computation often has to be performed in a trusted execution environment, and which requires tamper-proof hardware. If the mechanism of the computing system can be tampered with, we may no longer be able to trust the correctness and reliability of this computation. We consulted and studied with the idea of using this computing system platforms for a high security application as a means to protect data from physical access. We studied the whole application requirements of such a high security application, the operating environment, the cost of deployment, the debug situati ..read more
