Program suspend/resume for memory

摘要

A memory device includes a memory array with a plurality of memory elements. Each memory element is configured to store data. The device includes an input/output (I/O) buffer coupled to the memory array. The I/O buffer is configured to receive data from an I/O interface of a memory device controller and write the data to the memory array. The device includes a memory control manager coupled to the memory array. The memory control manager is configured to pause a program operation to the memory array in response to receiving a pause command. The memory control manager is also configured to resume the program operation in response to receiving a resume command.

1. An apparatus comprising:
an input/output (I/O) interface configured to couple the apparatus to an I/O buffer coupled to memory elements of a memory device, the I/O buffer residing on the same die as the memory elements; a program module coupled to the I/O interface, wherein the program module is configured to issue an instruction to the memory device to program user data to the memory device via the I/O buffer; and a program suspend module coupled to the I/O interface, wherein the program suspend module is configured to: issue at least one command to the memory device, the at least one command configured to suspend only a specified subset of one or more physical pages of a program operation executing within the memory device in response to receiving a memory read request from an application to perform a read operation on the memory device on which the program operation is being executed; and issue at least one command to the memory device, the at least one command configured to resume the program operation in response to completing the operation associated with the memory access request.
