Disclosed are a memory management system and a method thereof. Restricted spare cells are optimally distributed (or allocated) into a physical region and a virtual region in a system for repairing a fault of a memory, thereby increasing a yield of a memory chip.

Memory management system and method thereof

Disclosed are an analyzing system for managing an information storage table and a control method thereof. That is, each of the physical basic regions, which are units of hashing an information storage position, is divided into a plurality of physical sub regions having same size. Then, a combination of virtual basic regions which satisfy a predetermined target value is checked from all configurable combinations and a hash value related with the combination of the virtual basic regions which satisfies the checked target value is stored in a predetermined region of a memory. Therefore, even though an information storage space required for every unit region is overloaded, when there is an extra information storage space in another region, the information storage space having an extra space is used to maximize efficiency of the information storage space.

Analyzing system for managing information storage table and control method thereof

Disclosed are a memory apparatus having a plurality of information storage tables managed by separate virtual regions and a control method thereof. That is, a fault repair is applied in a memory system having a plurality of information storage tables managed by a separate virtual region, so that the entire information storage space is uniformly used for every region to improve a performance of the entire system and maximize efficiency of the information storage space by utilizing the information storage space.

Memory apparatus having plurality of information storage tables managed by separate virtual regions and control method thereof

Provided are a memory apparatus for applying fault repair based on a physical region and a virtual region and a control method thereof. That is, the fault repair is applied based on the physical region and the virtual region which use an information storage table of a virtual basic region using a hash function, thereby improving efficiency of the fault repair.
