Apparatuses and methods for providing data from a buffer

摘要

Apparatuses and methods for providing data from a buffer are disclosed herein. An example apparatus may include an array, a buffer, and a memory control unit. The buffer may be coupled to the array and configured to store data. The data may include data intended to be stored in the storage area. The memory control unit may be coupled to the array and the buffer. The memory control unit may be configured to cause the buffer to store the data responsive, at least in part, to a write command and may further be configured to cause the buffer to store the data intended to be stored in the storage area in the storage area of the array responsive, at least in part, to a flush command.

1. An apparatus, comprising:
a memory array including an area designated as a storage area for persistent data storage; a buffer coupled to the memory array and configured to store data to the memory array, the buffer including a plurality of cache lines, each cache line of the plurality of cache lines configured to store data, wherein each of the cache lines of the plurality of cache lines includes a usage field configured to store information indicating whether the cache line includes data to be stored in the storage area of the memory array; and a memory control unit coupled to the array and the buffer, the memory control unit configured to cause the buffer to store the data responsive, at least in part, to a write command, the memory control unit further configured to identify data stored in the buffer as data to be stored in the storage area based on the information stored in the usage field and further configured to cause the identified data to be stored in the storage area of the array responsive, at least in part, to a flush command, the memory control unit further configured to interrupt the flush command to prepare for a read command or the write command and resume the flush command once the read command or the write command is performed.
