Abstract

A memory controller that controls a nonvolatile memory in response to commands from a host, includes a normal transfer queue and a priority transfer queue, a transfer packet priority determination unit, a transfer queue selector, and a transfer packet selector. The transfer packet priority determination unit determines whether a transfer packet is a priority packet based on transmission information of the transfer packet. The transfer queue selector selects the priority transfer queue and stores the transfer packet in the priority transfer queue when the transfer packet is determined as the priority packet, and selects the normal transfer queue and stores the transfer packet in the normal transfer queue when the transfer packet is not determined as the priority packet. The transfer packet selector transfers to a host a priority packet stored in the priority transfer queue preferentially with respect to a normal packet stored in the normal transfer queue.

Abstract

A method is for verifying a logic operation of a target circuit including a circuit module configured to dynamically switch between synchronous transfer and asynchronous transfer. The method includes setting a time window for detecting an erroneous change of a logical value of a data signal. The time window ranges a first time period forward and a second time period backward from an edge of a clock signal and excludes a certain sub range. The method includes, during a simulation, determining whether or not the erroneous change of the logical value of the data signal is detected during the set time window. The method includes, upon detection of the erroneous change, inserting an erroneous sample into a test vector for the simulation, and upon non detection of the erroneous change, continuing the simulation without inserting the erroneous sample.

Abstract

According to one embodiment, a memory system receives from a host read commands each designating both of a block address of a read target block and a read target storage location in the read target block, and executes a data read operation in accordance with each of the received read commands. In response to receiving from the host a first command to transition a first block to which data is already written to a reusable state of being reusable as a new write destination block, the memory system determine whether an incomplete read command designating a block address of the first block exists or not. In a case where the incomplete read command exists, the memory system executes the first command after execution of the incomplete read command is completed.

According to one embodiment, a memory system determines a write destination block and a write destination location in the write destination block to which write data is to be written, and notifies a host of an identifier of the write data, a block address of the write destination block, and an offset indicative of the write destination location. The memory system retrieves the write data from a write buffer of the host, and writes the write data to the write destination location. In a case where a read command to designate a physical address of first data is received before a write operation of the first data is finished, the memory system reads the first data from the write buffer of the host.
