    摘要: A NAND cell type electrically erasable programmable read-only memory has a memory array section containing NAND cell units. Each NAND cell unit has a series array of floating gate type metal-oxide semiconductor field effect transistors as memory cell transistors. The memory section is associated with a control-gate controller, a data-latch circuit, a sense amplifier section, and a data comparator, which is connected via an output buffer to a verify-termination detector. When a data is once written into a selected memory cell in a data programming mode, a specific basing voltage is applied to the selected cell so that the actual electrical data write condition of the selected memory cell is verified. If the comparator detects that the verified write condition is dissatisfied, data-rewriting operations are repeatedly executed by additionally supplied the selected cell with a suitable voltage which compensates for the dissatisfaction of the verified write condition in the selected memory cell transistor.

    摘要: A semiconductor storage apparatus and a method of writing data to the semiconductor storage apparatus can restrict the threshold value of the memory cells, to which data has been written or from which data has been erased, to be included in a predetermined range without excessive writing by performing a verifying operation. In the writing operation, writing is performed such that a first determining level is set to a loose level which is the same as the level set for the reading operation or higher than the loose level but lower than a finally required determining level. In accordance with the first determining level, a first writing operation is performed. Then, a second writing operation is performed in accordance with a second determining level. The threshold value of a memory cell having a threshold value between the first determining level, which is the loose level, and the second determining level which is the required determining level (an aimed determining level) is raised to be higher than the second determining level, that is, the writing operation is performed by two steps. When the width of the distribution of the threshold values is reduced, data can reliably be erased from all of the memory cells when data is collectively erased in the erasing operation.

    摘要: A sense amplifier for signal detection for use in an electrically erasable and programmable read-only memory (EEPROM). The sense amplifier includes a first clock signal-synchronized inverter including a first inverter and first switch for switching between activating and deactivating states of the first inverter, the first clock signal-synchronized inverter having a first input connected to a corresponding one of the bit lines and a first output. A second clock signal-synchronized inverter is arranged in parallel with the first clock signal-synchronized inverter and includes a second inverter and a second switch for switching between activating and deactivating states of the second inverter, the second clock signal-synchronized inverter having an input connected to the output of the first clock signal-synchronized inverter and an output connected to the input of the first clock signal-synchronized inverter. The switches in the first and second clock signal-synchronized inverters are activated with a delay so that a potential on the corresponding bit line is reliably sensed and latched at the output of the first clock signal-synchronized inverter.

    摘要: A non-volatile semiconductor memory device includes a flip-flop circuit for holding write data in one of first and second states. A bit line is connected to the flip-flop circuit via a switching element and a transistor charges the bit line. A non-volatile memory cell, connected to the bit line and having a MOS transistor structure, stores data when a threshold thereof is set in one of first and second threshold ranges, wherein at the time of a write mode the threshold of the memory cell is shifted from the first threshold range towards the second threshold range while the flip-flop circuit remains in the first state and the shift of the threshold is not effected while the flip-flop circuit remains in the second state, and at the time of a verify mode following the write mode the bit line is kept at a charge potential by the charging transistor while the threshold remains in the second threshold range. A data setting circuit connects one of first and second signal nodes of the flip-flop circuit to a predetermined potential when the bit line is at the charge potential in the verify mode, thereby setting the flip-flop circuit in the second state irrespective of the state prior to the verify mode.
