Industrial Flash Memory

Industrial flash memories are very in demand in the industrial world because of their low power consumption (compared to mechanical hard drives) and their small size. As they do not contain any moving parts, they are very quiet and insensitive to shocks and vibrations. Our memory modules and cards meet the high requirements of the industry.
We offer industrial storage solutions in all form factors and capacities:
- Memory cards (SD and MicroSD cards, Compactflash, CFast, USB stick)
- SSD (2.5 "and 1.8", SATA and PATA / IDE)
- Embedded modules (U.2, M.2, Slim SATA, mSATA and eUSB)
- DRAM modules (DDR4, DDR3, DDR2, DDR and SDRAM)
- PCMCIA cards (SRAM, Linear Flash, ATA Flash) and drives

Our portfolio includes products from well-known manufacturers such as ATP, Innodisk, Swissbit, Transcend, UD Info, or Cactus Technologies. Because flash memories are sometimes exposed to extreme thermal loads, these manufacturers offer the commercial temperature range from 0°C to +70°C as well as the extended temperature range from -40°C to + 85°C.

Our flash memories are available with the following NAND technologies:
- SLC NAND (single-level cell)
- pSLC or iSLC NAND (pseudo single-level cell)
- MLC NAND (Multi-Level Cell)
- TLC NAND (Triple-Level Cell)


SLC memory cells (Single-Level Cell) only store 1 bit per cell. Only 2 charge states per capacitor are used here. This ensures a long service life for the data storage devices with low power consumption. SSDs with SLC NAND flash are often used for write-intensive storage requirements because of their high reliability and low susceptibility to errors. They are particularly suitable for critical industrial applications in which data security has top priority.


pSLC stands for pseudo single-level cell. The pSLC data memories physically consist of MLC (2 bits per cell) or TLC (3 bits per cell) NAND flash, which are, however, addressed logically like SLC NAND flash (1 bit per cell). This means that pSLC NAND has a 13 times longer service life, 1.5 time higher performance and 5 times longer data retention time than MLC NAND.
Although pSLC storage media have a significantly lower data density than MLC and TLC storage media, they offer a multiple in durability, performance and better data retention. Especially where very high storage capacities and a long service life (many write-erase cycles) are required, pSLC storage solutions are an inexpensive alternative to SLC.


With MLC (Multi-Level Cell) 2 bits are stored per cell. This means that the storage density is 50% lower than with TLC, but 100% higher than with SLC NAND flash memory, where only 1 bit is stored per cell. Data memories with MLC NAND flash have a higher write/read speed and are less error-prone than data memories with TLC. At the same time they are less expensive than SLC.


TLC (Triple-Level Cell) are NAND-Flash memory cells, on each of which 3 bits are stored. An SSD or memory card with TLC NAND flash has 50% more storage space with the same number of cells than an SSD with MLC NAND flash (which only stores 2 bits per cell). TLC NAND flash storage media are low-priced (per gigabyte) and offer very high capacities.
