Abstract: A system and apparatus for secure NVM format by pre-erase is disclosed. According to certain embodiments when an NVM does into idle mode, one or more free blocks are serially popped from a free block heap. The free block is then physically erased in an SLC mode, and then pushed to a pre-erase heap. The process is performed in both SLC and TLC partitions, in the TLC partition the block becomes hybrid SLC (HSLC). This process increases a program erase count (PEC) value of the block, maintaining device longevity. When there is a need to use a new block, it is popped from the pre-erase heap. In some cases where there is a need to use a TLC block instead of an HSLC block, an erase operation is used that converts the block from HSLC to TLC, and does not increase a PEC value for the block.

Abstract: A storage system and method for predictive block allocation for efficient garbage collection are provided. One method involves determining whether a memory in a storage system is being used in a first usage scenario or a second usage scenario; in response to determining that the memory is being used in the first usage scenario, using a first block allocation method; and in response to determining that the memory is being used in the second usage scenario, using a second block allocation method, wherein the first block allocation method allocates blocks that are closer to needing garbage collection than the second block allocation method.

Abstract: A storage device and method for detecting and handling burst operations are provided. In one embodiment, a method for operating a storage device in burst mode is provided. The storage device senses a change in behavior of a host in communication with the storage device, determines whether the sensed change in behavior of the host is indicative of the host's need for the storage device to operate in burst mode by comparing the sensed change in behavior with prior changes in behavior that triggered prior burst modes in the storage device, and in response to determining that the sensed change in behavior of the host is indicative of the host's need for the storage device to operate in burst mode, operates the storage device in burst mode. Other embodiments are provided.
