    • PURPOSE: A nonvolatile memory is provided to reduce a number of circuit by decreasing a voltage of a control gate of a floating gate-typed memory cell. CONSTITUTION: A periphery circuit of a floating gate-typed cell comprises a writable and erasable floating gate-typed cell(21) and floating gate-typed cell(22), P channel transistors, and an inverter(25). The periphery circuit of floating gate-typed cell sets a critical voltage of one cell to below 0 V and maintains a critical voltage of the other cell in a normal state, to store a data by voltage differences flowing the two floating gate-typed cells. Control gates of the cells are inputted with 0 V from the power, and one of the memory transistor is always maintained an on-state. The cells have a polysilicon gate in a gate oxide film as the prior art to implant or radiate electron by applying high voltage and to change the critical voltage of the memory transistor.
    • 目的:提供非易失性存储器以通过降低浮动栅型存储单元的控制栅极的电压来减少电路数量。 构成:浮动栅型单元的外围电路包括可写和可擦除浮栅型单元(21)和浮栅型单元(22),P沟道晶体管和逆变器(25)。 浮栅型电池的外围电路将一个电池的临界电压设置为低于0V,并将另一个电池的临界电压维持在正常状态,以通过流过两个浮动栅极类型电池的电压差来存储数据。 电池的控制栅极从电源输入0V,并且存储晶体管中的一个始终保持导通状态。 电池在栅极氧化膜中具有多晶硅栅极,作为现有技术,通过施加高电压来注入或辐射电子并改变存储晶体管的临界电压。

    • The ROM circuit comprises a first transistor having a control and a floating gate and a depletion type second transistor having a gate formed as an extension of the floating gate. The second transistor outputs a high level control signal if hot electrons have been accumulated on the floating gate of the first transistor by the application of a predetermined high level input signal to the control gate, and outputs a low level signal when the high level input signal has not been provided to the control gate. A resistor is connected between the control gate and drain of the first transistor, and a second resistor is connected between the output node of the second transistor and the second voltage surce.
