initialize the second amount of the system memory;

start the operating system load process; and

initialize an additional amount of the system memory in parallel with the operating system load process.

9. A method of managing memory, comprising:

determining a first amount of a memory needed for a boot process;

initializing the first amount of the memory;

starting the boot process;

initializing an additional amount of the memory in parallel with the boot process;

patrol scrubbing the memory; and

allocating more than one write credit to the patrol scrubbing.

10. The method of claim 9 , wherein any of the initializing comprises:

the patrol scrubbing the memory.

11. The method of claim 10 , wherein the patrol scrubbing the memory comprises:

writing full cache lines of zeros to the memory without reading the memory.

12. The method of claim 10 , further comprising:

retrieving a first parameter corresponding to an amount of the memory needed for the boot process;

determining the first amount of the memory in accordance with the retrieved first parameter;

retrieving a second parameter corresponding to an amount of write credits to allocate to the patrol scrubbing; and

allocating the amount of the write credits to the patrol scrubbing in accordance with the retrieved second parameter.

13. The method of claim 9 , further comprising:

allocating more than fifty percent of write credits to the patrol scrubbing.

14. The method of claim 9 , further comprising:

determining a second amount of the memory needed for an operating system load process after the boot process;

initializing the second amount of the memory;

starting the operating system load process; and

initializing an additional amount of the memory in parallel with the operating system load process.

15. At least one non-transitory computer readable medium, comprising a set of instructions, which when executed by a computing device, cause the computing device to:

determine a first amount of a memory needed for a boot process;

initialize the first amount of the memory;

start the boot process;
