Problems solved by technology

This results in an increase in the time period required for the storage device to respond to a write request or a read request from the host device
In other words, the operating speed of the storage device and the computing device including the storage device is reduced

Abstract

The invention discloses a storage device and an operating method of the storage device. An operating method of a storage device that includes a nonvolatile memory device and a controller configured to control the nonvolatile memory device includes sending map data from the storage device to a host device, the map data mapping one or more of a plurality of physical addresses of the nonvolatile memory device to one or more of a plurality of logical addresses of the host device; receiving, at the storage device, a read request from the host device; if the read request includes a physical address, reading data from the nonvolatile memory device based on the included physical address; and if the read request does not include a physical address, translating a logical address of the read request into a first physical address, and reading data from the nonvolatile memory device based on the translated first physical address.

Description

technical field [0001] At least some example embodiments of the inventive concepts described herein relate to a semiconductor memory, and more particularly, to a memory device including a nonvolatile semiconductor memory and a controller, a method of operating the memory device, and accessing the memory device. The access method of the device. Background technique [0002] A storage device refers to a device that stores data under the control of a host device such as a computer, smartphone, or smart tablet. A storage device includes a device that stores data on a magnetic disk such as a hard disk drive (HDD), or a device that stores data on a semiconductor memory, particularly a non-volatile memory such as a solid state drive (SSD) or a memory card. [0003] Nonvolatile memory includes read-only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM), flash memory devices, phase-change RAM (PRAM), magneti...
