Semiconductor memory devices including error correction circuits and methods of operating the semiconductor memory devices
摘要：
A memory controller includes a controller input/output circuit configured to output a first command to read first data, and output a second command to read an error corrected portion of the first data. A memory device includes: an error detector, a data storage circuit and an error correction circuit. The error detector is configured to detect a number of error bits in data read from a memory cell in response to a first command. The data storage circuit is configured to store the read data if the detected number of error bits is greater than or equal to a first threshold value. The error correction circuit is configured to correct the stored data.
摘要（中）：

存储器控制器包括：控制器输入/输出电路，被配置为输出第一命令以读取第一数据，并输出第二命令以读取第一数据的纠错部分。 存储装置包括：误差检测器，数据存储电路和纠错电路。 错误检测器被配置为响应于第一命令来检测从存储器单元读取的数据中的错误位数。 如果检测到的错误比特数大于或等于第一阈值，则数据存储电路被配置为存储读取数据。 误差校正电路被配置为校正存储的数据。
