In 1966, Dr. Robert H. Dennard at the IBM Thomas J. Watson Research Center was working on MOS memory. It typically refers to devices in which data is stored within metal-oxide-semiconductor (MOS) memory cells on a silicon integrated circuit memory chip. While examining the characteristics of MOS technology, he found it was capable of building capacitors, and that storing a charge or no charge on the MOS capacitor could represent the 1 and 0 of a bit, while the MOS transistor could control writing the charge to the capacitor. This led to his development of a single-transistor DRAM memory cell. Currently this type of memory has not been widely commercialized, but it is expected to be a competitor for flash memory. Read only memory (ROM) is an example of nonvolatile memory. Under the export control regulations imposed by the U.S., a license is required for items destined for any semiconductor fabrication facility in China that makes chips of certain specifications, including dynamic random access memory, or DRAM, chips of 18 nanometers or less, NAND flash memory chips with 128 layers or more, and logic chips of 16 nm, 14 nm or below.
