摘要:
A memory capable of suppressing increase of a chip area thereof while preventing nonselected subarrays from disturbance is obtained. This memory comprises a first transistor for connecting respective sub bit lines with each other, and connects the sub bit lines of the nonselected subarrays with each other through the first transistor and connects the same to fixed potentials arranged on both ends of a memory cell array at least in a read operation.

A memory includes a first holding circuit holding a first address of first data, a second holding circuit holding at least one of a second address of the first data and the amount of the first data, and an operation control circuit performing an operation rewriting the first address, an operation rewriting the second address or the amount of the first data and an operation continuously holding the first address and the second address or the amount of the first data.
摘要:
A memory capable of suppressing reduction of data determination accuracy is provided. This memory includes a memory cell connected to a bit line for holding data and a bipolar transistor whose base is connected to the bit line. In data reading, the memory reads the data by amplifying a current, corresponding to the data of the memory cell, appearing on the bit line with the bipolar transistor.

摘要:
A memory capable of preventing a memory cell from disappearance of data resulting from accumulated disturbances is obtained. This memory comprises a nonvolatile memory cell and a refresh portion for rewriting data in the memory cell. The refresh portion reads data from and rewrites data in the memory cell in a power-down state.
