Abstract: A storage device manages a read look ahead (RLA) buffer with fluctuating RLA caching. The storage device includes a memory device to store data in a format including upper, middle, and lower pages and an RLA buffer to store data retrieved from the memory device. When a controller on the storage device receives a host read request, the controller predicts data to be included in a subsequent host read request. The controller then determines a set of pages storing the predicted data, identifies latency-oriented pages in the set of pages, retrieves data from the latency-oriented pages, and stores the data in the RLA buffer. When the storage device receives the subsequent host read request including the predicted data, the controller reads a first portion of the predicted data from the RLA buffer and a second portion of the predicted data from the memory device.

Abstract: A data storage system includes control circuits configured to connect to nonvolatile memory cells and to a host. The control circuits are configured to perform a first data recovery operation in response to reading uncorrectable data from the nonvolatile memory cells. The control circuits are configured to inform the host, within a time limit for responding to a host read command from the host, of the failure of the first data recovery operation and availability of a second data recovery operation.

Abstract: A method for the synthesis of OSL grade polycrystalline mass of ceramic materials with dopant C involving source ceramic material preferably in its readily available powder form comprising the steps of melting of the said ceramic material in graphite environment including a graphite crucible/container in vacuum; and obtaining there from polycrystalline aggregate by rapid solidification of said melt to thereby provide said polycrystalline mass of ceramic materials with dopant C of optically stimulated luminescence grade. The said powder form of the ceramic material is compacted and formed into pellets before subjecting to melting.

Abstract: Presented herein is a system, method, and apparatus for firmware code-coverage in complex system on chip. A circuit for analyzing code coverage of firmware by test inputs comprises an input and a memory. The input receives an address from a code address bus. The memory stores recorded addresses from the code address bus. The memory comprises a plurality of memory locations, each of the memory locations mapped to a particular one of a corresponding plurality of addresses associated with the firmware. The contents of the memory location associated with the address received from the code address bus being incremented responsive to receipt of the address.

Abstract: The present invention relates to a process for the isolation of artemisinin, an antimalarial agent from the herb of the Artemisia annua plant, comprising of extracting the herb with ethanol, partitioning of the extract between water and hexane, followed by evaporative crystallization of artemisinin from hexane phase to produce substantially pure artemisinin.
