摘要: A method is provided for biasing a NAND array EEPROM during programming to allow the array to be scaled down further before reach punchthrough. The sources of the ground-select transistors of the NAND array are biased at V.sub.cc instead of ground to reduce the voltage drop across the source and drain of the ground-select transistors. As a result, the channel length of the ground-select transistors can be further shortened before punchthrough is obtained, resulting in a higher density EEPROM.

摘要: A method of reading a memory cell, and a memory array using the method, are described. An electrical load is applied to a first node in the memory array, the first node corresponding to the memory cell. A second node in the memory array, the second node on a same word line as the first node, is precharged. The second node is separated from the first node by at least one intervening node in the same word line.

摘要: A microprocessor chip is adapted to maintain its databus at a reference voltage level during idle times between outputs. The arrangement enables like pull-up and pull-down delays as well as low noise levels to be achieved in the output circuits.
