Nand Flash The basic principles have been introduced in my articles from May and August of 2025. Therefore, we know that when using and programming Nand Flash, the most important aspects are Bad Block management, the use of Spare Area, and the selection of the ECC error checking and correction mechanism. Before 2015, customers had … Read more
00 Introduction NAND Flash is a type of non-volatile storage medium where charge is stored in a floating gate surrounded by an insulating layer, allowing it to retain stored data even when power is lost. It utilizes a “NOT-AND Gate” circuit structure, with storage cells connected in series. From smartphones to solid-state drives, it plays … Read more
According to whether data can continue to be stored in the device after power loss, storage chips can be divided into volatile and non-volatile types.Volatile storage chips mainly include Static Random Access Memory (SRAM) and Dynamic Random Access Memory (DRAM).Non-volatile memory mainly includes Programmable Read-Only Memory (PROM), Flash Memory (Flash), and Erasable Programmable Read-Only Memory … Read more

1. The main categories can be divided into two major camps: NAND Flash and DRAM1. NAND Flash manufacturers These chips are used in devices that require long-term data storage, such as SSDs, USB drives, SD cards, and mobile storage. Currently, the global market is mainly dominated by the following companies, often referred to as the … Read more
NAND Flash cannot achieve XIP, which is entirely determined by its underlying hardware implementation technology and interface standards, rather than something that can be easily changed by software or the operating system. This stands in stark contrast to NOR Flash, which supports XIP, with the core difference being the access interface and addressing method.Interface Bus:NOR … Read more
Core Insights AI servers are reshaping the global supply and demand landscape for storage chips, with HBM (High Bandwidth Memory) becoming the most scarce strategic resource. DDR5 and enterprise-grade NAND Flash are also benefiting from the growth in demand. In the context of accelerated domestic substitution, the main investment lines in A-shares are clearly differentiated:Tongfu … Read more
