ACCELERATING BOOT TIME ZEROING OF MEMORY BASED ON NON-VOLATILE MEMORY (NVM) TECHNOLOGY

摘要

Methods and apparatus to accelerate boot time zeroing of memory based on Non-Volatile Memory (NVM) technology are described. In an embodiment, a storage device stores a boot version number corresponding to a portion of a non-volatile memory. A memory controller logic causes an update of the stored boot version number in response to each subsequent boot event. The memory controller logic returns a zero in response to a read operation directed at the portion of the non-volatile memory and a mismatch between the stored boot version number and a current boot version number. Other embodiments are also disclosed and claimed.

1. An apparatus comprising:
a storage device to store a boot version number corresponding to a portion of a non-volatile memory; and memory controller logic, coupled to the non-volatile memory, to cause an update of the stored boot version number in response to each subsequent boot event, wherein the memory controller logic is to return a zero in response to a read operation directed at the portion of the non-volatile memory and a mismatch between the stored boot version number and a current boot version number.
