Abstract: In a memory system where memory units may be separated from each other so as to operate substantially independently, the coordination of related memory operations between such units may be by synchronization of an epoch of time and the start of an epoch of time with a common synchronization source. The source may be distributed directly to each of the memory modules of a memory unit, or through an intermediate synchronization circuit of a memory unit that is common to the modules. Where the data is stored as a RAID stripe on a plurality of synchronized modules, the read and write or erase operations performed by the modules may be arranged such that the write operations or erase operations may not substantially affect the ability to promptly read the stored data of a RAID stripe.

Abstract: A memory system having a plurality of modules operated so that a group of memory modules may operation in a RAID configuration having an erase hiding property. The RAID groups are mapped to areas of memory in each of the memory modules of the RAID group. More than one RAID group may be mapped to a memory module and the erase operations of the RAID groups coordinated such that the erase operations do not overlap. This may improve the utilization of a bus over which the memory module communicates with the controller. Where a memory module is replaced by a memory module having an increased storage capacity, the additional storage capacity may be mapped to an expanded logical address space.

Abstract: A memory system and a method for managing the system is described. The system is configured such a plurality of system controllers, which may be RAID controllers, receive requests from the external environment and distribute the requests to a plurality of memory modules such that data may be stored in the memory modules. A global sequence number is assigned to the data of a data stripe so that the operations related to the data stripe are performed in an ordered manner so that the data remains consistent. A plurality of system controllers may comprise a domain and access a plurality of memory controllers and a plurality of domains may include at least one common memory module. A plurality of groups of controllers may communicate with a switch or with a representative controller so as to coordinate the assignment of global sequence numbers.
