NAND CONTROLLER

The PATA NAND Controller is the heart of a high-performance, flash media-based data storage system. The NAND Controller recognizes the control, address and data signals on the ATA/IDE bus and translates them into memory accesses to the standard NAND-type flash media. The GLS55LD040M device supports Single-Level Cell (SLC) and Multi-Level Cell (MLC) flash media. This technology is ideal for solid state mass storage applications offering expanded functionality, flexible capacity scaling capabilities and lower power consumption.The PATA NAND Controller supports standard ATA/IDE protocols with up to PIO Mode-4, Multi-word DMA Mode-2, and Ultra DMA Mode-6 interface. It directly supports up to 16 flash media devices or, through simple decoding logic, supports up to 64 flash media devices.
