Controller and operating method thereof

A method for operating a controller, the method comprising:

• sequentially receiving a plurality of input data, each including a pattern for identifying data for a corresponding input period of a plurality of input periods;
• setting, as a reference pattern, a pattern included in any one data among the plurality of input data;
• generating a control signal, based on whether correspondence data including the same pattern as the reference pattern is input;
• storing the plurality of input data in a shift register in a sequence in which the plurality of input data are input, wherein, when the correspondence data among the plurality of input data is stored, outputting capture data that are stored data including the correspondence data based on the control signal,
• wherein the generating of the control signal further includes:
• storing the reference pattern that is a pattern included in any one data among the plurality of input data;
• and
• generating the control signal, based on whether any one of the patterns respectively included in the plurality of input data corresponds to the reference pattern, when the correspondence data including the same pattern as the reference pattern is input multiple times, changing the status of the control signal from an inactive status to an active status, based on a set correspondence number, and outputting the control signal which is changed to the active status.

A controller comprising:

• a data receiver configured to receive a plurality of input data, each including a pattern for identifying data;
• a pattern determiner configured to set, reference patterns, patterns included in at least two data among the plurality of input data, and generate a control signal, based on whether correspondence data including the same patterns as the reference patterns are input;
• and
• a data storage configured to store the plurality of input data in a sequence in which the plurality of input data are input, and, when the correspondence data are stored, output capture data that are stored input data including the correspondence data, based on the control signal,
• wherein the pattern determiner includes:
• a reference pattern storage configured to store a pattern set as the reference pattern;
• and
• a pattern comparator configured to output the control signal based on whether any one of the patterns included in the plurality of input data corresponds to the reference pattern,
• wherein the data storage includes:
• a shift register configured to store the plurality of input data sequentially received from the data receiver;
• and
• a mode controller configured to determine whether new input data is to be stored in the shift register or whether the data stored in the shift register are to be output, based on the control signal, and
• wherein, when the correspondence data is input multiple times, the pattern comparator changes the status of the control signal from the inactive status to the active status based on a set correspondence number, and outputs the control signal which is changed to the active status.

A memory system comprising:

• a memory device;
• and
• a controller suitable for:
• sequentially receiving a plurality of input data from a host, the plurality of input data including a pattern for identifying data for a corresponding input period of a plurality of input periods;
• setting, as a reference pattern, a pattern included in any one data among the plurality of input data;
• generating a control signal, based on whether correspondence data including the same pattern as the reference pattern is input;
• sequentially storing the plurality of input data in an order in which the plurality of input data are input,
• wherein the generating of the control signal further includes:
• storing the reference pattern that is a pattern included in any one data among the plurality of input data;
• and
• generating the control signal, based on whether any one of the patterns respectively included in the plurality of input data corresponds to the reference pattern,
• wherein, when the correspondence data including the same pattern as the reference pattern is input multiple times, changing the status of the control signal from an inactive status to an active status, based on a set correspondence number, and outputting the control signal which is changed to the active status.
