Abstract: A method and apparatus for read wearing control for storage class memory (SCM) are disclosed. The read data control apparatus, located between a host and the SCM subsystem, comprises a read data cache, an address cache and an SCM controller. The address cache stores pointers pointing to data stored in logging area(s) located in the SCM. For a read request, the read wearing control determines whether the read request is a read data cache hit, an address cache hit or neither (i.e., read data cache miss and address cache miss). For the read data cache hit, the requested data is returned from the read data cache. For the address cache hit, the requested data is returned from the logging area(s) and the read data becomes a candidate to be placed in the read data cache. For read data cache and address cache misses, the requested data is returned from SCM.

The at least one first DC-to-DC converter is coupled to the at least one renewable power source and the DC bus. The bi-directional DC-to-DC converter is coupled to the rechargeable battery assembly and the DC bus. The controller controls power electricity feeding into and being drawn from the DC bus, thereby keeping a bus voltage of the DC bus substantially fixed at a system voltage.

Abstract: A method and apparatus of bad location management for storage class memory are disclosed. A nonvolatile memory is partitioned into a non-reserved space and a reserved space, which are divided into multiple data units. The health status of the data units in the non-reserved space are classified into multiple classes including a mostly-good class. For host data read, the data from a mostly-good data unit are read and whether the data includes a pointer is checked. If no pointer, the data read are returned as the host data. Otherwise, the data unit pointed by the pointer is read. For data write, the data from a mostly-good data unit are read. If no pointer in the read data, the host data are written into the mostly-good data unit. Otherwise, the host data are written into the data unit in the reserved space pointed by the pointer.
