H10B ELECTRONIC MEMORY DEVICES
Introduced: January 2023
Description
H10B covers semiconductor-based memory devices and solid-state storage technologies that do not fall within other specific H10 classifications. This includes volatile memory types such as RAM variants, as well as non-volatile memory technologies like flash memory, EEPROM, and other solid-state storage media used for data retention and retrieval. The classification encompasses the structural design, operational principles, and technical characteristics of these electronic memory devices at the component level. Adjacent classes address more specialized memory architectures or memory-related circuit functions handled separately within the H10 hierarchy.
IPC and CPC are identically structured here. All 12 subcodes exist in both systems.
1 shared codes have differing titles between IPC and CPC.
IPC defines codes here since 2023.
