摘要： A nonvolatile semiconductor memory with a unit cell structure suitable for high speed operation and a low power supply voltage. The nonvolatile semiconductor memory includes a switching circuit including block select transistors connected by its respective terminal to a corresponding bit line. This switching circuit transmits a signal only when a string to which the switching circuit corresponds is selected. A second active region having a different impurity concentration from a first active region constituting source and drain regions of memory transistors is formed at a substrate contact portion of a bit line contact portion where the memory string and bit line are connected. The impurity concentration of the second active region is lower than that of the first active region.

摘要： A semiconductor memory device which is comprised of a plurality m of electrically isolated data memory sub-arrays for storing data bits and a plurality k of electrically isolated parity memory sub-arrays for storing parity bits, wherein each of the data and parity memory sub-arrays includes a plurality of memory cells arranged in a matrix of rows and columns, with the memory cells in each row connected to a common word line and the memory cells in each column connected to a common bit line. Row address decoders function to activate a selected word line in each of the memory sub-arrays, and column address decoders, in combination with column selection circuitry, function to couple a selected bit line in each of the memory sub-arrays to a plurality m of sense amplifiers, which function to sense the voltage level of respective ones of the selected bit lines, and produce output data and parity bits representative of these sensed voltage levels. An error checking and correction circuit compares the output data and parity bits in order to detect and correct errors in the output data bits. Because of the unique architecture of the semiconductor memory device of this invention, defects in word lines or bit lines are confined to a single bit, thereby rendering these defects easily reparable by means of an ECC circuit alone, and thus dispensing with the need for a redundant memory circuit.

摘要： A polysilicon gate electrode of an integrated circuit field effect transistor is formed in two portions which are isolated from one another. The first portion is formed on the gate insulating region. The second portion is formed on the semiconductor substrate outside the gate insulating region and is electrically insulated from the first portion. Since the first and second portions of the polysilicon gate electrode are isolated from one another, only the charge which is on the first polysilicon portion contributes to gate insulating region degradation during plasma etching. After polysilicon gate electrode formation, the first and second portions may be electrically connected by a link. Field effect transistor performance and/or reliability are thereby increased.
