Problems solved by technology

Also, because access to data is provided in smaller units (eg, in a manner more like fast byte-addressable volatile memory and less like slow, sector-addressable hard drives), the data path The importance of waiting time increases further
For example, an operation that provides access to large blocks of data may have a reasonable latency period that may be too long for an operation that provides access to a few bytes of data in small bursts

Embodiment Construction

[0016] Aspects of the present disclosure are embodied as apparatuses, systems, methods or computer program products. Accordingly, aspects of the present disclosure may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, microcode, etc.), or an embodiment combining software and hardware aspects, which may all be referred to herein collectively as "circuit", "module", "device", or "system". Furthermore, aspects of the present disclosure may be in the form of a computer program product embodied as one or more non-transitory computer-readable storage media storing computer-readable and / or executable program code.

[0017] Many of the functional units described in this specification have been labeled as modules, to more particularly emphasize their implementation independence. For example, a module may be implemented as a hardware circuit comprising custom VLSI circuits or gate arrays, off-the-shelf semiconducto...

Abstract

Apparatuses, systems, and methods are disclosed for controlling a data path for non-volatile memory. An apparatus includes one or more memory die. A memory die includes a memory core. A memory core includes an array of non-volatile memory cells and an internal data pipeline. A memory die includes a buffer that stores data associated with storage operations for a memory core. A memory die includes an internal controller that communicates with a memory core to initiate storage operations. An internal controller may delay initiating a storage operation in response to determining that an internal data pipeline and a buffer are both full.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 278,227, filed January 13, 2016, by Jingwen Ouyang et al., entitled "DATA-PATHCONTROL WITH INTERNAL CLOCK AND ASYNCHRONOUS FIFO," which is hereby incorporated by reference. technical field [0003] The present disclosure relates, in various embodiments, to non-volatile memory, and more particularly to controlling data paths of non-volatile memory. Background technique [0004] The amount of time it takes a nonvolatile memory element to service or perform a storage operation may include the time it takes to actually sense or change the physical characteristics of a nonvolatile memory cell to read or write data, the amount of time it takes to transfer data on a data bus time, and additional latencies in the data path for internally moving address information and / or data within the non-volatile memory element for filling buffers for store op...
