Introduction to Envoy Data Memory Technologies

Envoy Data Memory is a leading provider of industrial-grade memory and storage solutions that offer a wide range of cutting-edge technologies. These technologies are essential for manufacturers that rely on robust storage technology to meet their business needs. In this table, we will introduce and briefly address all of the technologies that Envoy Data Memory supports and why they are crucial to businesses that require reliable and durable storage solutions.



3D NAND3D NAND is a type of non-volatile flash memory in which the memory cells are stacked vertically in multiple layers. This technology provides higher storage capacity, faster read/write speeds, and lower power consumption compared to traditional planar NAND.
Power Loss Protection (PLP)Power Loss Protection (PLP) ensures that data is not lost during sudden power failures. This technology provides a temporary power source to store data in the event of an unexpected power loss.
Flash Module with DRAM BufferA DRAM chip in a flash module functions the way a cache does in a hard disk. This technology enhances the performance of flash memory by using DRAM as a buffer.
Advanced LDPC ECC EngineAdvanced Low-Density Parity Check (LDPC) Error Correction Code (ECC) is an error-correcting mechanism that detects and corrects errors that occur during data transfer.
DEVSLPDevSleep is a new addition to the SATA specification, which enables SATA-based storage solutions to reach a new level of low-power operation. This technology reduces power consumption and extends battery life in mobile devices.
Dynamic Thermal ThrottlingThis mechanism is used to prevent SSD from overheating. The SSD controller dynamically adjusts the performance of the drive to maintain a safe operating temperature.
End-to-End Data ProtectionEnd-to-End Data Protection is an effective methodology to ensure data integrity. This technology uses a combination of error detection and correction codes to prevent data corruption during data transfer.


Flash Life MonitorFlash Life Monitor is a monitoring software developed to monitor flash disk health. It tracks the wear level of the flash memory and provides early warnings of potential failures.
Pseudo SLCpSLC technology uses MLC NAND but with a special firmware that changes cell storage at the block level simulating SLC technology. This technology provides faster write speeds, longer endurance, and better reliability than standard MLC NAND.
Bad Block ManagementBad block management is regularly performed on NAND flash memory. This technology isolates bad blocks and redirects data to good blocks, ensuring data integrity and preventing data loss.
Over-ProvisioningSSD overprovisioning can provide higher efficiency and better endurance. This technology allocates additional storage capacity for wear leveling, bad block management, and garbage collection.
S.M.A.R.TSelf-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) is a monitoring system that detects and reports on various parameters of the drive's health, such as temperature, error rate, and wear level.
WAF ReductionMinimize Write Amplification to Maximize SSD Lifetime. This technology minimizes write amplification by grouping smaller writes into larger ones, reducing the number of program/erase cycles.
Wear LevelingSSD controllers use a technique called wear leveling to distribute writes as evenly as possible across all the flash blocks in the SSD. This technology extends the life of the SSD by preventing certain blocks from wearing out faster than others.


Wide and Automotive
Envoy Data Memory's Wide Temperature flash and memory modules are designed for extreme environments, capable of withstanding temperatures from -40˚C to 85˚C. This technology ensures that data is safe and secure even in the harshest of conditions. Automotive Temperature available on certain products up to 105C
Conformal CoatingConformal coating is a thin protective film applied to products to protect against moisture, dust, chemicals, and sunlight. This technology protects the components from environmental hazards and extends the life of the product.


Write ProtectWrite protection is used to denote the locking mechanism which prevents modification or deletion of data on a storage device. This technology ensures that data remains safe from unauthorized access.
AES 256-bit and FIPS 140-2 Hardware EncryptionAES 256-bit encryption refers to the process of concealing plaintext data using the AES algorithm and an AES key length of 256 bits. This technology provides strong encryption and ensures that data remains secure and confidential. FIPS 140-2 options also available on certain products.


Form FactorsEnvoy Data Memory's flash, DRAM modules, and modular expansion cards form factors are made to fit in the compact, limited space of the system. This technology provides flexibility in design and allows for the use of memory and storage solutions in these devices.
