Abstract:
1. A memory system, comprising: a dual inline memory module (DIMM) connector to which a DIMM is connected, the DIMM being selected from a Joint Electron Device Engineering Council (JEDEC) standard DIMM in compliance with JEDEC standards and a customized DIMM not in compliance with JEDEC standards; and a memory controller to determine whether the DIMM being connected is the JEDEC standard DIMM or the customized DIMM to generate a determination result, and to control access to the DIMM based on the determination result and serial presence detect (SPD) information obtained from an SPD of the DIMM being connected, wherein when the determination result indicates that the DIMM being connected is the JEDEC standard DIMM, the memory controller determines whether a setting value of the SPD information is correctly set according to the JEDEC standard, and when the setting value of the SPD information is not correctly set according to the JEDEC standard, the memory controller does not enable the access to the DIMM, and when the determination result indicates that the DIMM being connected is the customized DIMM, even if the setting value of the SPD information is not correctly set according to the JEDEC standard, the memory controller enables the access to the DIMM.
