Samsung patents memory that writes data at two different speeds
Samsung has been granted a patent for a storage device that allows a controller to choose between a standard writing speed and a slower, distinct writing speed for non-volatile memory. The system uses specific commands to tell the memory chips how long they should take to process data, adjusting the time the controller waits for a completion signal.
In the filing’s own words
A storage device includes a storage controller configured to transmit either a normal program command or a slow program command to a non-volatile memory via data lines, and the non-volatile memory comprising a plurality of non-volatile memories. Each of the plurality of non-volatile memories is configured to output a ready/busy signal to the storage controller during a first program time in response to the normal program command, and output a ready/busy signal to the storage controller during a second program time, the second program time being is different from the first program time, in response to the slow program command.
What exactly they claim (claim 1)
1. A storage device comprising: a storage controller configured to transmit either a normal program command or a slow program command to a non-volatile memory via data lines; and the non-volatile memory comprising a plurality of non-volatile memories, wherein each of the plurality of non-volatile memories is configured to output a ready/busy signal to the storage controller during a first program time in response to the normal program command, and output a ready/busy signal to the storage controller during a second program time, the second program time being different from the first program time, in response to the slow program command.
