Abstract: A storage device including: a non-volatile memory device including at least one memory die, wherein the at least one memory die includes a plurality of memory regions, each region inputting and outputting a first data signal and a second data signal; and a memory controller including an eye open monitoring (EOM) circuit configured to perform a first EOM operation of generating first EOM information based on the first data signal and a second EOM operation of generating second EOM information based on of the second data signal of at least one of the regions, and configured to compare the second EOM information with the first EOM information, and control the at least one memory die based on a result of the comparison of the first EOM information and the second EOM information.

Abstract: In a method of writing data in a storage device, a data write request is received from a host device. Spatial information is received from a spatial sensor included in the storage device based on the data write request. A logical storage area management table is updated based on the data write request and the spatial information such that target data to be stored is written into a target storage area corresponding to the spatial information among a plurality of logical storage areas. A program command and the target data are transmitted to a nonvolatile memory such that the target data is programmed into a physical storage area in the nonvolatile memory corresponding to the target storage area.
