Abstract
A selective data memory device includes skip and sequential read circuits that connect input/output lines for inputting and outputting string data, and data set corresponding to the string data, to bit lines. String bit registers temporarily store data on the string data line for inputting selecting string data, and bit comparators compare the string data on the bit lines of the memory cells with data stored in the string bit registers. The string data on the bit lines can be selected by the bit comparators. On the basis of the comparison results, specific data is written in a specific bit position of the bit lines by string match mark circuits. On the basis of the specific bit data, the skip and sequential read circuits can access the memory cells. Therefore, a key string data access is enabled, and it is possible to realize a large capacity memory device for enabling an effective data set access in match with key string data.
