Abstract
Memory modules having accurate operating parameters stored thereon and methods for fabricating and implementing such devices to improve system performance. Memory modules comprising a number of volatile memory devices may be fabricated. Operating parameters for specific memory devices on the memory module or a specific lot in which the memory devices are fabricated may be stored on a non-volatile memory device on the memory module. A system may be configured in accordance with the operating parameters stored on the non-volatile memory device such that corresponding thresholds are not exceeded.
Claims18
A method of operating a memory module comprising a volatile memory device, the method comprising:
- accessing the volatile memory device;
- monitoring an actual operating current of the volatile memory device;
- and
- comparing the actual operating current of the volatile memory device to operating current thresholds, wherein the operating current thresholds are based on operating currents uniquely corresponding to a lot in which the volatile memory device was manufactured.
A method of operating a memory module comprising a volatile memory device, the method comprising:
- accessing the volatile memory device;
- monitoring an actual operating current of the volatile memory device;
- and
- comparing the actual operating current of the volatile memory device to operating current thresholds, wherein the operating current thresholds are based on operating currents uniquely corresponding to the volatile memory device.
A method of configuring a system comprising:
- reading operating parameters from a non-volatile memory device on a memory module, wherein the memory module comprises a plurality of volatile memory devices, and wherein the operating parameters uniquely correspond to a lot in which the volatile memory devices were manufactured;
- and
- configuring the system in accordance with the operating parameters from the non-volatile memory device on the memory module:
- wherein the operating parameters comprise operating current values that uniquely correspond to the lot in which the volatile memory devices were manufactured.
A method of configuring a system comprising:
- reading operating parameters from a non-volatile memory device on a memory module, wherein the memory module comprises a plurality of volatile memory devices, and wherein the operating parameters uniquely correspond to each of the plurality volatile of memory devices;
- and
- configuring the system in accordance with the operating parameters from the non-volatile memory device on the memory module;
- wherein the operating parameters comprise operating current values that uniquely correspond to each of the plurality of volatile memory devices.
