Methods and systems for memory page allocation

A computer program product comprised of a series of instructions executable on a computer, the computer program product performing a process for improving memory page allocation;

• the computer program implementing the steps of:
• generating, using a compression unit, compressed grains associated with compressed blocks;
• identifying a write page allocation unit to query;
• receiving, at the write page allocation unit, a query for a flash memory location to store the compressed grains;
• determining a flash memory location for the compressed grains;
• determining a parity location for the compressed grains;
• returning offsets indicating the flash memory location and the parity location;
• sending the compressed grains to the free grain location and a parity bit to the parity location as part of an atomic transaction;
• and
• recording a start location of compressed grains in a mapping.

A system for improving memory page allocation, the system comprising:

• a storage media device;
• a PCIe-based device controller associated with the storage media device, wherein the PCIe-based device controller is configured to:
• generate, using a compression unit, compressed grains associated with compressed blocks;
• identify a write page allocation unit to query;
• receive, at the write page allocation unit, a query for a flash memory location to store the compressed grains;
• determine a flash memory location for the compressed grains;
• determine a parity location for the compressed grains;
• return offsets indicating the flash memory location and the parity location;
• send the compressed grains to the free grain location and a parity bit to the parity location as part of an atomic transaction;
• and
• record a start location of compressed grains in a mapping.
