Techniques for storing digital data in an analog or multilevel memory

摘要: An integrated circuit stores analog or digital information, both, in memory cells (416). The provide multilevel storage. Analog information is provided through an signal input (405), and a (407). A scheme for storing consistent with the used to store information. Data retrieved from cells, output (454, 463) depending on type of data. reference generator (425) generates various equivalent voltages input.
