    Abstract: PROBLEM TO BE SOLVED: To obtain a memory having a burst mode reading function and a page mode reading function while erasing or programming one sector in a semiconductor memory having two or more memory sectors S1-S9. SOLUTION: This semiconductor memory is provided with first control circuit means 4, 6 for controlling the electrical change operation of contents of a memory. The first control circuit means 4 (6) can execute selectively the operation for changing electrically one content of a memory sector and can interrupt the execution so as to be possible to reading-access the other memory sectors. The memory is characterized by providing second control circuit means 8, 6 which can permit burst mode reading or page mode reading operation for reading contents of the other memory sectors.

    Abstract: Semiconductor device comprising at least two pads (101, 102; 103, 104) for the input of external signals and/or for the output of signals from said semiconductor device, at least two uncoupling buffers (201, 202; 203, 204) each connected to each one of said pads, at least one multiplexer (10; 20) connected to said pads (101, 102; 103, 104) by means of said uncoupling buffers (201, 202; 203, 204) and at least one memory element (4; 5) suitable to generate a configuration signal (C ) operating on said multiplexer (10; 20) and said uncoupling buffers (201, 202; 203, 204) to selectively enable one or the other of said pads (101, 102; 103, 104).
