Samsung has recently unveiled a 32 GB NAND flash memory. With the announcement of the 32 GB NAND flash memory, Samsung has shown its muscle in the world of flash memory. Based on the 20nm manufacturing process, Samsung has produced the first ever NAND chips. Based on the multi level cell (MLC) NAND technology, the NAND chips can be used in SD memory cards and in other devices that use or need embedded memory. Samsung has already started shipping memory cards based on the (MLC) NAND technology and is planning expand the production of these chips later in 2010.

The Samsung NAND chips are 20nm class MLC NAND chip and the productivity level of the Samsung 20nm-class MLC NAND is 50 percent higher than the Samsung 30nm-class MLC NAND. The Samsung 20nm-class MLC NAND of 8 GB or higher density SD card possesses 30 percent faster rate than Samsung 30nm-class NAND and delivers read speed o 20 MB/s and write speed of 10 MB/s. Samsung has secured the reliability level of 20nm-class MLC NAND by applying the cutting edge process, design and controller technology as compared to the Samsung’s 30nm-class NAND.

The Korean based electronics manufacturer, Samsung Electronics began the production of 32 GB NAND with 30nm-class process technology in March 209 and now it has started shipping the samples of chips based on the 20nm-class 32GB NAND technology. The memory cards based on the 20nm-class 32GB NAND technology will be available in minimum density of 4 GB and in maximum density of 64 GB. Samsung is also looking forward to produce chips based on the (MLC) NAND technology in large quantity so that the users will be getting these NAND chips at a cheaper cost.

With the introduction of such high performance NAND chips, Samsung has supported the growth of memory of high density for various products like smartphones and other devices that need and support memory.
