Title: Dynamic ram
Inventor: CHO SHIZUO
IPC: G11C7/00
Filed: 1988-06-28
Abstract: PURPOSE:To increase the access speed by selectively making a pair of bit lines and a pair of sense amplifier nodes conductive or non-conductive in response of a control signal. CONSTITUTION:Transistors TRs T5 and T6 of a TR gate 91 set one sense amplifier node and the pair of bit lines to the conductive state and set the other to the conductive state after setting it to the non-conductive state in response to a signal phiL at the time of sense operation of sense amplifiers 73 and 75. A TR gate 101 couples the pair of sense amplifiers and a pair of data busses when sense amplifier nodes and bit lines are switched from the non- conductive state to the conductive state at the time of amplifying operation of sense amplifiers. By this constitution, the sensing operation is performed without being affected by the bit line capacity, and the discharging time is shortened in the amplifying operation to increase the access speed.

IPC: H01L27/115
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To significantly shorten a readout time in an readout error check by simultaneously operating a plurality of word lines to perform a readout check of data. SOLUTION: A predetermined test data pattern is recorded in a memory cell array of an EEPROM in which a data is held in a NAND-type memory cell array. A word line of a cell transistor which holds data '1' is set to be 'L', while a word line of a cell transistor which holds data 'O' is set to be 'H'. By providing such a condition that the whole unit column of NAND cells, in which the cell transistors are connected in series, turns on, it is determined whether a NAND column turns on. This is performed by pre-charging a bit line BL to Vcc and observing how charges are reduced. In addition, a memory cell holding data 'O' with which the cell transistor does not turn on in the respective NAND blocks is selected by a normal manner so as to confirm whether the condition is satisfied.
