Aitech M222 - High Density Solid State Flash Memory PMC

Provides up to 64 GB of Mass Storage in a Single Industry Standard PMC Slot.


The Aitech M222 is a high capacity Flash memory PMC utilizing advanced high-performance, high-capacity NAND Flash devices to provide up to 64 GB of mass storage in a single industry standard PMC slot.

The board incorporates no moving parts, delivering significantly lower power consumption and higher reliability as compared to hard drive storage solutions.

The PMC PCI interface provides 66 MHz/64-bit data access, and supports master/target functionality over the PCI bus. As PCI master it utilizes its integrated DMA engine for block transfer modes.

Throughput of up to130 MB/s is achieved when DMA transfer mode is used to interface with a fast host interface (at the carrier) via the M222 PLX PCI-to-Local Bus Bridge. (Note that performance is dependant on operation mode, Host Bridge capabilities, and software overhead.)

The M222 software package includes the Aitech Flash Low Level (FLL) driver technology, which provides support for basic Flash read/write/erase operations as well as additional features for basic data protection and bank interleaving for enhanced performance. The optional Aitech Flash Memory Manager (FMM) goes one step further, providing full hard drive emulation, wear leveling, and Error Correction Code (ECC) to ensure data integrity. The FMM employs a unique write-forward mechanism to achieve higher performance than standard file system software packages.
