Samsung patents memory trick to flip data for better reading
This filing describes a method for storing data in memory chips that use a specific type of circuit called a single-ended bitline sense amplifier. The system checks if most bits in the incoming data are one value or the other; if so, it flips the entire data pattern before saving it and keeps a small note to remember the flip.
In the filing’s own words
A method of storing data in a memory device including a single-ended bitline sense amplifier includes receiving input data; determining logic levels of bits included in the input data; generating a data inversion flag corresponding to the input data in response to a first number of bits of the input data having a first level being greater than a second number of bits of the input data having a second level; inverting the input data into complementary input data; storing the complementary input data in a memory cell array; and storing the data inversion flag in a specified partial area of the memory cell array.
What exactly they claim (claim 1)
1. A method of storing data in a memory device including a single-ended bitline sense amplifier, the method comprising: receiving input data; determining logic levels of bits included in the input data; generating a data inversion flag corresponding to the input data in response to a first number of bits of the input data having a first level being greater than a second number of bits of the input data having a second level; inverting the input data into complementary input data; storing the complementary input data in a memory cell array; and storing the data inversion flag in a specified partial area of the memory cell array.
