Abstract
A data retention operation of holding positive hole groups generated by an impact ionization phenomenon or by a gate-induced drain leakage current in a semiconductor base body is performed by controlling voltages applied to plate lines, word lines, a source line, odd-numbered bit lines, and even-numbered bit lines; and a data erase operation is performed by removing positive hole groups from inside the semiconductor base body by controlling the voltages applied to plate lines, word lines, source line, odd-numbered bit lines, and even-numbered bit lines and lowering a voltage of The semiconductor base body by means of capacitive coupling between the plate lines and word lines. A block is made up of memory cells arrayed in a matrix, and storage data is read from the memory cells in the block alternately to the odd-numbered bit lines and even-numbered bit line.
