Memory system and method for efficient padding of memory pages

摘要

In one embodiment, a memory system is provided comprising a memory die and a controller. The memory die comprises a non-volatile memory, a data latch, and an on-chip randomizer. The controller is configured to send a command to the memory die to cause the on-chip randomizer to store random data in the data latch and send data to the memory die to overwrite some, but not all, of the random data in the data latch, wherein the memory die is configured to transfer the data and random data stored in the data latch to the non-volatile memory. Other embodiments are provided.

1. A memory system comprising:
a memory die comprising:
a non-volatile memory;a data latch; andan on-chip randomizer; and a controller in communication with the memory die, wherein the controller is configured to:
send a command to the memory die to cause the on-chip randomizer to store random data in the data latch; andsend data to the memory die to overwrite some, but not all, of the random data in the data latch; wherein the memory die is configured to transfer, from the data latch to the non-volatile memory, the data and the random data that has not been overwritten by the data.
