Translation lookaside buffer in a switch
View Patent ↗Examples of the present disclosure provide apparatuses and methods related to a translation lookaside buffer in memory. An example method comprises receiving a command including a virtual address from a host translating the virtual address to a physical address on volatile memory of a memory device using a translation lookaside buffer (TLB).
1. An apparatus, comprising:
a number of memory devices including a number of vaults, each of the number of vaults including a partition of memory from each of the number of memory devices; and
a logic base on which the number of memory devices are stacked, the logic base including:
a switch configured to provide availability of collective bandwidth from the number of vaults; and
a translation lookaside buffer (TLB) located on the switch;
the logic base is configured to perform, in response to receipt of a command including a virtual address, a virtual address to physical address translation to translate the virtual address to a physical address in one of the number of memory vaults using the TLB, wherein a physical address corresponding to the virtual address is searched only in the TLB.
2. The apparatus of claim 1 , wherein each of the number of vaults is functionally and operationally independent of other vaults.
3. The apparatus of claim 1 , wherein each of the number of vaults is coupled to a corresponding one of a number of vault controllers, and wherein the number of vault controllers are configured to manage memory operations for a respective one of the number of vaults.
4. The apparatus of claim 1 , wherein the logic base is configured to use the TLB to translate no more than a number of bits to identify the physical address on the one of the number of memory vaults.
5. The apparatus of claim 1 , wherein the logic base is configured to use the TLB to map the virtual address of the command directly to the physical address on the memory device.
6. The apparatus of claim 1 , wherein the command is received from a requesting device.
7. The apparatus of claim 1 , wherein the logic base is configured to remap, to update the TLB, a relationship between virtual and physical addresses in response to data in the number of memory devices being moved.
8. An apparatus, comprising:
a number of memory devices including a number of vaults; and
a logic base on which the number of memory devices are stacked, the logic base including:
a switch configured to provide availability of collective bandwidth from the number of vaults;
a translation lookaside buffer (TLB) located on the switch; and
a number of vault controllers, each of the number of vault controllers coupled to a corresponding one of the number of vaults, and wherein each of the number of vault controllers is configured to perform, in response to receipt of a command including a number of virtual addresses, a virtual address to physical address translation to translate the number of virtual addresses of a command to a number of physical addresses in the number of memory devices using the TLB, wherein a physical address corresponding to at least one of the number of virtual addresses is searched only in the TLB.
9. The apparatus of claim 8 , wherein the number of vaults controllers are coupled to a memory control unit, and wherein the memory control unit is configured to consolidate functions of the number of vaults of the number of memory devices.
10. The apparatus of claim 8 , wherein the command is received from a requesting device, and wherein the switch is coupled to a link interface controller that controls an input/output (I/O) link to the requesting device.
11. The apparatus of claim 8 , wherein each of the number of vaults includes a partition of memory from each of the number of memory devices.
12. The apparatus of claim 8 , wherein the number of physical addresses of the number of memory devices includes each addressable physical address of the number of memory devices.
13. The apparatus of claim 8 , wherein the command is received from a host.
