Embodiment Construction

[0046] The following disclosure provides many different embodiments, or examples, for implementing different features of the presented subject matter. Specific examples of components and arrangements are described below for the purpose of simplifying the present disclosure. Of course, these components and arrangements are examples only and are not intended to be limiting. For example, in the following description, forming a first feature over or on a second feature may include embodiments in which the first feature is formed in direct contact with the second feature, and may also include embodiments in which the first feature is formed in direct contact with the second feature. Embodiments where additional features may be formed between features such that a first feature may not be in direct contact with a second feature. In addition, the present disclosure may repeat drawing numerals and / or letters in various instances. This repetition is for simplicity and clarity and does...

Abstract

Disclosed herein are related to operating a memory system including memory banks and buffers. Each buffer may perform a write process to write data to a corresponding memory bank. In one aspect, the memory system includes a buffer controller including a queue register, a first pointer register, a second pointer register, and a queue controller. In one aspect, the queue register includes entries, where each entry may store an address of a corresponding memory bank. The first pointer register may indicate a first entry storing an address of a memory bank, on which the write process is predicted to be completed next. The second pointer register may indicate a second entry to be updated. The queue controller may configure the queue register according to the first pointer register and the second pointer register, and configure one or more buffers to perform the write process, according to the entries.

Description

technical field [0001] The present disclosure relates to a system, and more particularly, to a buffer-controlled memory system for multiple memory banks. Background technique [0002] The development of electronic devices such as computers, portable devices, smartphones, internet of things (IoT) devices, etc. has led to an increase in demand for memory devices. In general, a memory device can be a volatile memory device or a non-volatile memory device. Volatile memory devices can store data while power is supplied, but may lose the stored data once power is removed. Unlike volatile memory devices, nonvolatile memory devices can retain data even after power is removed, but can be slower than volatile memory devices. Contents of the invention [0003] An embodiment of the present disclosure provides a memory system. The memory system includes multiple memory banks, multiple buffers, and a buffer controller. The buffer controller includes a queue register, a first pointer r...
