Abstract: In a method of allocating and protecting a memory in a computational storage device including a first computing engine and a buffer memory, a memory allocation request is received from a host device that is disposed outside the computational storage device. Based on the memory allocation request, a memory allocation operation in which a first memory region is generated in the buffer memory and a first key associated with the first memory region is generated is performed. A program execution request is received from the host device. Based on the program execution request, a program execution operation is performed in which a first program is executed by the first computing engine by accessing the first memory region based on an encryption or a decryption using the first key.

Abstract: A storage device includes a nonvolatile memory device and a storage controller. The storage controller includes a multi-protocol host interface circuit that receives a first-type request including a first logical address from an external host and transmits/receives data corresponding to the first-type request with the external host by a block unit. Additionally, the multi-protocol host interface circuit receives a second-type request including a first physical address from the external host and transmits/receives data corresponding to the second-type request with the external host by a unit smaller than the block unit. A mapping cache manager manages an address translation table cache, sends an address translation request including the first physical address to the external host, and receives a response including mapping information corresponding to the first physical address from the external host.

Abstract: A storage system includes a host and a storage device. The host includes a host processor and a host memory buffer, wherein the host processor includes a CPU core controlling operation of the host and a cache dedicated for use by the CPU core. The host memory buffer includes a submission queue and a completion queue. The storage device is connected to the host through a link and communicates with the host using a transaction layer packet (TLP). The storage device includes a nonvolatile memory device (NVM) and a storage controller, wherein the host writes a nonvolatile memory express (NVMe) command indicating a destination to the submission queue, and the storage controller reads data from the NVM, directly accesses the cache in response to destination information associated with the destination, and stores the read data in the cache.

Abstract: A memory device includes; a first memory of first type, a second memory of second type different from the first type, and a memory controller. The memory controller receives an access request and workload information related to work of an external processor, processes the access request using the workload information, and accesses at least one of the first memory and the second memory in response to the access request.
