8 . A system for managing functions, comprising:
a host comprising an application;
a storage device comprising a processing element, and a memory;

assigning a first memory range and a second memory range different from the first memory range to a physical memory, wherein the first and second memory ranges are memory-mapped to correspond to a first computational component and a second computational component different from the first computational component, respectively, for performing one or more computations on the storage device,
wherein the first and second memory ranges are allocated in the physical memory used in communication between a host and and a namespace of a local storage in the storage device;
receiving a first command to perform a first operation in the communication between the host and the namespace;
performing the first operation using the first memory range to generate first data;
receiving, based on the performing, from the application on the host, a second command for managing the first memory range;
performing, by the storage device, the second command on the first data stored on the physical memory via at least one processing element in the storage device associated with the namespace to generate second data, wherein the second data is stored at a location of the first data;
transmitting, by the storage device, third data based on the second data to the host; and
receiving, based on the transmitting, a third command to perform a second operation using the first memory range.
9 . The system of claim 8 , wherein the second command comprises an operation to set at least a portion of first data to a predetermined bit, and the third data comprises a completion indication.
10 . The system of claim 8 , wherein the memory comprises volatile memory or non-volatile memory located within the storage device and the operation further comprises virtualizing the volatile memory or non-volatile memory.
11 . The system of claim 10 , wherein the operations further comprise communicating, to the host, via a virtual address associated with the volatile memory.
12 . The system of claim 10 , wherein the operations further comprise dedicating a portion of the virtualized memory for the first operation or for a first duration.
13 . The system of claim 8 , wherein the command comprises a command generated by an application on the host and received via an API.
14 . The system of claim 8 , wherein the storage device comprises an NVMe enabled storage device or an NVMe-oF enabled storage device.
15 . A non-transitory computer-readable medium storing instructions that, when executed by a computer, cause the computer to perform operation for managing a memory of a storage device, the operations comprising:
assigning a first memory range and a second memory range different from the first memory range to a physical memory, wherein the first and second memory ranges are memory-mapped to correspond to a first computational component and a second computational component different from the first computational component, respectively, for performing one or more operations on the storage device,
wherein the first and second memory ranges are allocated in the physical memory used in communication between a host and a namespace of a local storage in the storage device;
receiving a first command to perform a first operation in the communication between the host and the namespace;
performing the first operation using the first memory range to generate first data;
receiving, based on the performing, from the host, a second command for managing the first memory range;
