固态硬碟控制电路及相关的固态硬碟装置与固态硬碟存取系统;SOLID STATE DRIVE CONTROLLING CIRCUIT AND RELATED SOLID STATE DRIVE DEVICE AND SOLID STATE DRIVE ACCESS SYSTEM

摘要

本发明提出一种固态硬碟控制电路及相关的装置与系统，该固态硬碟控制电路包含：进阶主机控制器介面(AHCI)控制电路，用于耦接快速周边组件互连(PCIe)介面；以及快闪记忆体控制电路，耦接于AHCI控制电路，设置成控制固态硬碟中的一或多个快闪记忆体阵列的存取运作。AHCI控制电路会透过PCIe介面，传送用于代表AHCI控制电路耦接于M个固态硬碟的指示信息至主控装置。前述M为大于1且小于32的正整数。;A solid state drive (SSD) controlling circuit and related SSD device and SSD access system are disclosed.The SSD controlling circuit includes: an advance host controller interface (AHCI) controlling circuit for coupling with a peripheral component interconnect express (PCIe) interface; and a flash memory controlling circuit coupled with the AHCI controlling circuit and configured to operably control accessing operations of one or more flash memory arrays of a solid state drive.The AHCI controlling circuit transmits an indication message to a host device through the PCIe interface, wherein the indication message represents that the AHCI controlling circuit is coupled with M solid state drives.The aforementioned M is an integer greater than 1 and less than 32.
