Samsung Electronics has just announced that they have started producing 20nm-class NAND chips for use in SD memory cards and embedded solutions. The new process, improving upon a 30nm process, brings better performance and density for storage solutions. A new 32Gb (gigabit) MLC NAND chip adds to Samsung’s portfolio of storage solutions.
According to Samsung, the 20nm MLC NAND chips have 50 percent higher productivity level than the previous generation 30nm NAND. The write performance of an 8GB SD card is 30% faster than the 30nm-class based SD cards. This gives the memory a speed-level rating of 10 (20MB/s read, 10MB/s write). Reliability levels are equivalent to those found in the 30nm-class.
The first 20nm-class produced chips were completed in March and samples are now shipping to customers. Production of the new chips will expand this fall. Memory cards using the 20nm chips will range in capacity from 4GB to 64GB.
