The GLS55LD040M NAND Controller is the heart of a high-performance, flash media-based data storage system. The GLS55LD040M 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 Controller 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 while enabling smaller, lighter designs with lower power consumption.
