## Abstract

A memory card includes a first ground terminal arranged in a first row that provides a ground voltage to at least one nonvolatile memory or a memory controller, universal flash storage (UFS) terminals arranged in a second row including a first UFS terminal that provides a second power, a second UFS terminal that provides a reference clock signal, and a third UFS terminal that provides a path for input/output data to the memory controller, and a first power terminal arranged in a third row that provides a first power supply voltage (VCC) to the at least one nonvolatile memory or the memory controller. The memory card has a size defined by a nano subscriber identification module (SIM) card standard, the first ground terminal corresponds to a “C5” terminal of the nano SIM card standard, and the first power terminal corresponds to a “C1” terminal of the nano SIM card standard.
