Abstract: A read time-out manager may include a counter and a plurality of timers. The counter may generate a counter output signal based on a first cycle time. The plurality of timers may be each configured to be assigned a read identification to measure a time-out period corresponding to the read identification. Each of the plurality of timers may operate in synchronization with the counter output signal to generate a time-out signal based on a second cycle time different from the first cycle time.

Abstract: A buffer system may include a buffer configured to receive input data having an assigned priority level, store the input data within a memory stack regardless of the priority level assigned to the input data, and sequentially output the input data stored in the memory stack in order of the priority levels assigned to the input data.

Abstract: A semiconductor memory system includes a memory medium and a data input/output (I/O) pin repair control circuit. The memory medium includes a plurality of memory dies and a spare die. Each of the plurality of memory dies has a plurality of memory regions and a plurality of data I/O pins, and the spare die has a plurality of spare regions and a plurality of data I/O pins. The data I/O pin repair control circuit performs a repair process for replacing an abnormal data I/O pin among the plurality of data I/O pins included in any of the plurality of memory dies with a data I/O pin of the plurality of data I/O pins included in the spare die.

Abstract: A memory system includes a memory medium and a memory controller. The memory medium includes data symbols and parity symbols which are respectively disposed at cross points of a plurality rows and a plurality of columns. The memory controller includes an error correction code (ECC) engine that is designed to execute an error correction operation at a fixed error correction level while the memory controller accesses the memory medium. The memory controller performs the error correction operation at the fixed error correction level using the ECC engine in a first error correction mode. The memory controller performs the error correction operation at an error correction level higher than the fixed error correction level using the ECC engine in a second error correction mode.
