    • PURPOSE:To prevent a defect due to the end of the lifetime of a nonvolatile memory with simple constitution, by storing the data replacing frequency to a nonvolatile memory then diagnosing whether or not the replacing frequency reaches a prescribed level. CONSTITUTION:When a power supply is closed, the contents of the ROM parts of the nonvolatile memories 3 and 4 are shifted to an RAM part via a recall circuit 6 to protect the ROM part. Then the data replacing frequency stored in the memories 3 and 4 are read out by a specified address and supplied to a CPU1 via a bus driver 5, etc. Thus it is diagnosed whether or not the data replacing frequency reaches the prescribed level. Then the contents of the memories 3 and 4 reaching the end of their lifetime are shifted to the other active memories 3 and 4 and stored there. As a result, it is possible to prevent the defect which is due to the change of data caused by the end of the lifetime of the nonvolatile memory.

    • PURPOSE:To reduce power consumption as an EPROM device, by preventing flow of current in common terminal at the time of reading. CONSTITUTION:When writing control signal -WE is high level with high voltage Vpp for writing impressed to a terminal Vpp/-OE, MOSFETQ6, Q7 become on, and output level of a voltage generating circuit 2 becomes low and MOSFETQ3 becomes off. When the signal -WE is made low level under this condition, MOSFETQ6, Q7 become off. Accordingly, high level signal of Vpp is transmitted to the voltage generating cirucit 2 through a condenser C, and the generating circuit 2 generates high voltage Vpp+alpha. MOSFETQ3 becomes on and writing pulse phiw is outputted. Consequently, DC current does not flow when reading, and power consumption can be reduced as an EPROM device.
    • 目的:通过在读取时防止公共端子中的电流流动,从而降低作为EPROM器件的功耗。 构成:当写入控制信号-WE为高电平,高电平Vpp写入端子Vpp / -OE时,MOSFETQ6,Q7变为导通,电压发生电路2的输出电平变低,MOSFETQ3变为关闭。 在这种情况下,当信号-WE为低电平时,MOSFETQ6,Q7变为关闭。 因此,通过电容器C将Vpp的高电平信号发送到产生电压的电压2,发电电路2产生高电压Vpp +α。 MOSFETQ3导通,并输出写入脉冲phiw。 因此,在读取时,直流电流不流动,并且作为EPROM器件能够降低功耗。

    • PURPOSE:To write many kinds of contents to plural ROMs in a short time, by reading out information to which a device information has been added, from an ROM of a main unit, and writing-in the information to an ROM of a subunit connected in parallel, corresponding to the device information. CONSTITUTION:Contents of each area of an ROM114 of a main unit 111 are read out in order through a controller 113, and an address information, a data information, and a device information for discriminating a subunit are outputted to a bus line 116 through an interface 115. As a result, the information is written in an ROM 19 of a corresponding sub-unit 112a- in the same way as the unit 111 connected in parallel with the line 116. Accordingly, many kinds of information contents are written in plural ROMs in a short time.

    • PURPOSE:To reduce current consumption in a memory part by applying a signal to read out the contents of a memory to the gate of a load FET and connecting latch circuits synchronized with a reading signal to a reading line. CONSTITUTION:Writing is executed by connecting the drains of MOSFETs Q1, Q4 as memory elements to data lines D1, D2. To read out the contents of a memory to a word line W2, the line W2 is turned to the H level, a word line W1 is turned to the L level and a reading signal terminal READ is turned to the H level. Consequently, p-MOSFETs Q5, Q6 as load elements are turned on, signals to the data input terminals D of latch circuits LAT1, 2 are sent from the output terminals Q, an memory output terminal O1 is turned to the H level similarly to the data line D1 and an memory output terminal O2 is tutned to the L level similarly to the data line D2, so that the contents of the memory are read out. When a reading signal terminal READ is turned to the L level, the Q5 and Q6 are cut off and the data are held in the latches LAT1, 2.
    • 目的:通过施加信号将存储器的内容读取到负载FET的栅极并将与读取信号同步的锁存电路连接到读取线路来减少存储器部分的电流消耗。 构成:通过将作为存储器元件的MOSFET Q1,Q4的漏极连接到数据线D1,D2来执行写入。 为了将存储器的内容读出到字线W2,将线W2变为H电平,字线W1变为L电平,读取信号端子READ变为H电平。 因此,作为负载元件的p-MOSFET Q5,Q6导通,从输出端子Q发送到锁存电路LAT1,2的数据输入端子D的信号,存储器输出端子O1与 数据线D1和存储器输出端子O2类似于数据线D2被限制到L电平,从而读出存储器的内容。 当读取信号端子READ变为L电平时,Q5和Q6被切断,数据被保持在锁存器LAT1,2中。
