Abstract

The invention provides an extension device and a storage system. The extension device comprises a first interface unit, at least one second interface unit and a control circuit, wherein the first interface unit is coupled to a controller; the at least one second interface unit is coupled to at least one memory; the control circuit is coupled to the first interface unit and the at least one secondinterface unit; the first interface unit is used for receiving a control command transmitted from the controller; and the control circuit is used for explaining a control command and controlling the at least one second interface unit to execute a corresponding action according to the control command.

Description

technical field [0001] The present application relates to a memory technology, and in particular to an expansion device and a storage system. Background technique [0002] In order to increase the capacity of the solid-state hard disk device, a plurality of flash memory chips are usually used in the solid-state hard disk, resulting in an increase in the number of input / output pads (I / Opads) used by the controller to couple to the flash memory. Therefore, the capacitance value of the input and output pads increases, and the operating frequency of the connection between the controller and the memory is difficult to maintain at the highest operating frequency of the controller. Contents of the invention [0003] One aspect of the present application is to provide an expansion device, which includes a first interface unit, at least one second interface unit, and a control circuit. The first interface unit is coupled to the controller, at least one second interface unit is cou...
