Samsung patents storage trick to keep data flowing during writes
Samsung describes a storage device that uses a controller to manage multiple memory chips. It allows the controller to send new data to one chip while another chip is busy moving data from a temporary holding area to its main storage.
In the filing’s own words
A storage device is provided. The storage device includes a storage controller and a plurality of non-volatile memories, where the storage controller is configured to transfer first logical page data of first page data to the first non-volatile memory through the channel while performing a program operation of page data comprising a plurality of pieces of logical page data, and transfer first logical page data of second page data to the second non-volatile memory through the channel while the first logical page data of the first page data from a cache latch of the first non-volatile memory is being dumped into a data latch of the first non-volatile memory.
What exactly they claim (claim 1)
1. A storage device comprising: a storage controller; and a plurality of non-volatile memories, wherein the plurality of non-volatile memories comprise a first non-volatile memory and a second non-volatile memory, the first non-volatile memory and the second non-volatile memory each connected to the storage controller through a channel, wherein the storage controller is configured to: transfer first logical page data of first page data to the first non-volatile memory through the channel while performing a program operation of page data comprising a plurality of pieces of logical page data, and transfer first logical page data of second page data to the second non-volatile memory through the channel while the first logical page data of the first page data from a cache latch of the first non-volatile memory is being dumped into a data latch of the first non-volatile memory.
