Micron Technology has announced the "Crucial M500" series of SSDs, based on new SSD 20nm NAND. The company also announced plans to release DDR4 memory modules in late 2013. The successor of the 25nm Crucial m4 series of SSDs, the Crucial M500 will most probably based on the Amrvell 88SS9187 controller with a customized firmware ny Micron, although not officially confirmed.



The M500 SSD utilizes Micron's 20-nanometer (nm) multilevel cell (MLC) NAND flash to achieve terabyte-class capacity and enable a new level of SSD price competitiveness; the company says its 960GB Crucial M500 SSD will be initially priced under $600.

The drives will be available in three form factors - 2.5-inch / 7mm, M.2 SSD modules and mSATA. The M.2 SSD module is a new form factor the size of a stick of gum, designed for ultrathin on-the-go computing. Capacities will range from 120-960GB.



In addition, Micron also announced the introduction of DDR4 SDRAM module in late 2013.

Designed to enable the next generation of enterprise and consumer products, Crucial DDR4 memory technology is engineered to pack more performance and has the capability to double the available density per module. Micron says that Crucial DDR4 modules will use up to 20% less voltage than previous technology, and will enable mainstream data rates that are at least twice as fast as DDR3 memory.

The DDR4 modules will operate at 1.2V and will be clocked at 2,133 MHz, with 4GB density per module.

At CES, Crucial, the global brand of Micron, demonstrated the Crucial Crucial Ballistix DDR4 DRAM modules, which were based on Micron's 30-nanometer (nm) technology. Micron's portfolio of DDR4-based modules will include RDIMMs, LRDIMMs, SODIMMs and UDIMMs.
