Abstract
Memory systems and operating methods of the memory systems are disclosed. In an implementation, a memory system includes a system buffer including buffer areas to which addresses are allocated, and configured to store data in the buffer areas, and a buffer manager configured to designate an address of a buffer area in which a defect occurs as a defect address by comparing a first parity bit for data stored in the system buffer with a second parity bit that is obtained by a computation based on the data stored in the system buffer, and block access to the buffer area designated as the defect address.
