In a nonvolatile memory with block management system that supports update blocks with non-sequential logical units, an index of the logical units in a non-sequential update block is buffered in RAM and stored periodically into the non-volatile memory. In one embodiment, the index is stored in a block dedicated for storing indices. In another embodiment, the index is stored in the update block itself. In yet another embodiment, the index is stored in the header of each logical unit. In another aspect, the logical units written after the last index update but before the next have their indexing information stored in the header of each logical unit. In this way, after a power outage, the location of recently written logical units can be determined without having to perform a scanning during initialization. In yet another aspect, a block is managed as partially sequential and partially non-sequential, directed to more than one logical subgroup.

The present invention describes the use of two semiconductor layers, a thin film (TF) layer and a bulk Si wafer layer, to make high density and high speed merged logic and memory IC chips. The memory cells use three-dimensional (3D) SRAM structures.

A non-volatile memory is constituted from a set of memory planes, each having its own set of read / write circuits so that the memory planes can operate in parallel. The memory is further organized into erasable blocks, each for storing a logical group of logical units of data. In updating a logical unit, all versions of a logical unit are maintained in the same plane as the original. Preferably, all versions of a logical unit are aligned within a plane so that they are all serviced by the same set of sensing circuits. In a subsequent garbage collection operation, the latest version of the logical unit need not be retrieved from a different plane or a different set of sensing circuits, otherwise resulting in reduced performance. In one embodiment, any gaps left after alignment are padded by copying latest versions of logical units in sequential order thereto.
