Mostly read embedded OEM applications should consider the read disturb issue in addition to the endurance of the NAND memory when making a decision on which grade of flash memory to use.
Pseudo-SLC NAND uses MLC NAND in a single bit per cell mode, thereby giving it >6 times the endurance of the same MLC NAND cell used in its traditional two bit per cell operation. Cactus OEM Grade uses this pSLC and is an upgrade from our Commercial Grade which uses MLC NAND.
Cactus Technologies industrial-grade flash storage products are designed to operate in environments where temperature, shock, vibration and voltage fluctuations occur often and can cause abnormal operations on the device.
The development of NAND flash technology has, until recently, followed the path of traditional memory technologies in that each memory cell stores one bit of binary data.
Using flash memory-based storage devices can be very helpful for the system to achieve high performance under these environmental constraints.
This white paper explains why OEM customers should consider using industrial- grade flash storage products from Cactus Technologies for reliable mass storage needs.
There are some customers who have trouble with DMA mode transfers. This document serves as a troubleshooting guide for DMA mode usage in our products.
