Samsung patents memory chip that reads data and check info at once
Samsung describes a memory design where the main data and its accompanying check information are stored in separate sections of the chip. When the computer asks for data, the chip opens both sections at the same time to pull the information in parallel.
In the filing’s own words
A memory device includes a bank array including a plurality of memory cells, a row decoder connected to the bank array through a plurality of wordlines, and a column decoder connected to the bank array through a plurality of column select lines. The bank array may include a first region and a second region different from the first region. First metadata for first normal data stored in the first region is stored in the second region, and second metadata for second normal data stored in the second region is stored in the first region.
What exactly they claim (claim 1)
1. A method of operating a memory device having a bank array, the method comprising: receiving a read command to access normal data; in response to the read command, simultaneously activating a first set of column select lines assigned to a normal data region of the bank array and a second set of column select lines assigned to a metadata region of the bank array; and fetching the normal data from the normal data region and metadata corresponding to the normal data from the metadata region in parallel in response to simultaneously activating the first set of column select lines.
