SEMICONDUCTOR STORAGE DEVICE Russian patent published in 2010 - IPC G11C16/06 G11B23/00 H04N1/34 B41J2/00 

FIELD: information technologies.

SUBSTANCE: in case when value of input data for recording is more than value of existing data in memory matrix, semiconductor storage device permits recording of input data into memory matrix. Reading controller reads existing data from memory matrix and compares them to data for recording fixed in 8-bit latch register. In case when value of data for recording is more than value of existing data, incremental controller generates signal WEN1 to permit recording into controller of recording/reading and performs record of data for recording, fixed in 8-bit latch register, into memory matrix.

EFFECT: protection of semiconductor memory device against recording of input data in it, which do not satisfy specific requirements to data.
