NAND
A non-volatile flash memory technology widely used in solid-state drives and mobile device storage. It is a standardized commodity storage product.
Timeline (last 90 days)
The memory market is cyclical, stemming from supply-demand mismatch: DRAM and NAND are standardized commodity products, manufacturers' capacity expansion cycles are long (2-3 years), while demand-side fluctuations are large.
The Lexar Muse uses a custom ultra-thin PCB combined with high-density NAND flash chip stacking technology.
TBW represents host write volume rather than actual NAND erase cycles; due to the write amplification effect inside SSD controllers, actual NAND wear is higher than the figure suggested by TBW.
DRAM read/write latency is approximately 60–100 nanoseconds, while NAND flash read latency is typically on the order of 10–100 microseconds.
High Bandwidth Flash is an industry concept being explored that uses NAND flash combined with high-bandwidth interfaces to redefine AI memory hierarchies.
Flash memory has inherent advantages over DRAM in capacity density and cost, but has disadvantages in write endurance and latency.
Memory manufacturers have prioritized more capacity toward higher-margin AI memory products, causing the supply of ordinary DRAM and NAND for the consumer market to tighten.
The repair process involved the MaskROM mode of the RK3066 chip, NAND flash memory and FTL (Flash Translation Layer), corrupted system data, and file system repair.
Memory chips typically account for 15% to 25% of a smartphone's total bill of materials (BOM) cost.
Continuously rising prices for memory chips (DRAM and NAND flash) are driving a phenomenon known as 'chipflation'.
