Abstract
Memory controllers having a data buffer coupled to receive and hold data from a memory device, and an Error Correction Code (ECC) generator/checker coupled to the data buffer. The ECC generator/checker is configured to generate ECC codes for the data and to compare the generated ECC codes with ECC codes received with the data. The memory controllers are configured to permit different ECC coverage area sizes and/or different ECC code types for different portions of the memory device.
Claims20
A memory controller, comprising
- a data buffer coupled to receive and hold data from a memory device;
- an Error Correction Code (ECC) generator/checker coupled to the data buffer, wherein the ECC generator/checker is configured to generate ECC codes for the data and to compare the generated ECC codes with ECC codes received with the data;
- wherein the ECC generator/checker is configured to generate ECC codes using a particular ECC coverage area size for data received from a particular portion of the memory device;
- and
- wherein the memory controller is configured to modify the particular ECC coverage area size for the particular portion of the memory device.
