摘要： A DRAM adopting a single-intersection memory cell array having randomly accessible data registers accessed whenever the chip is accessed externally. When data items recorded in the data registers are simultaneously written in the memory cell array, the data items are encoded. When data items are read from the memory cell array into the data registers, the data items are decoded. The margin is enhanced because array noise derived from reading is reduced. In addition, the access time of the DRAM is also reduced.

摘要翻译： 采用具有随机访问的数据寄存器的单交叉存储单元阵列的DRAM，只要芯片被外部访问即可。 当记录在数据寄存器中的数据项被同时写入存储单元阵列时，对数据项进行编码。 当将数据项从存储单元阵列读入数据寄存器时，数据项被解码。 由于从读数导出的阵列噪声减小，因此边缘被增强。 另外，DRAM的存取时间也减少了。

摘要： A sense amplifier is constructed to reduce the occurrence of malfunctions in a memory read operation, and thus degraded chip yield, due to increased offset of the sense amplifier with further sealing down. The sense amplifier circuit is constructed with a plurality of pull-down circuits and a pull-up circuit, and a transistor in one of the plurality of pull-down circuits has a constant such as a channel length or a channel width larger than that of a transistor in another pull-down circuit. The pull-down circuit with a larger constant of a transistor is first activated, and then, the other pull-down circuit and the pull-up circuit are activated to perform the read operation.
