| 摘要 |
A method of accessing a semiconductor memory comprising ferroelectric memory FETs arranged as a matrix to allow write and/or read data to and from only an intended memory cell without the data in not-intended cells being destroyed by the application of a disturbing voltage to not-intended cells, even without providing each cell with a selection element. The method is characterized in that, when data are written to or read from memory cells Q1 through Q4 arranged as a matrix comprising ferroelectric memory FETs each having a ferroelectric layer on the gate side to constitute a semiconductor memory, a voltage of a direction opposite that of the voltage for writing or reading the data is applied, followed by the application of a voltage for writing or reading.
