METHOD FOR TRANSMITTING DATA USING A DATA ERROR CHUCK FUNCTION, A SEMICONDUCTOR MEMORY, AND A MEMORY SYSTEM USING THE DATA ERROR CHECK FUNCTION

摘要

PURPOSE: A method for transmitting data using a data error check function, a semiconductor memory and a memory system using the data error check function are provided to reduce check time and a circuit area by simplifying an error check logic.;CONSTITUTION: An error check circuit(310) generates an error check signal by an error check operation in a row direction and a column direction of a data group. An input/output circuit(320) transmits an error check signal to the outside through a data input/output pin and an error warning pin. A core block(330) includes a memory area for recording the data group.;COPYRIGHT KIPO 2012
