Raw flash for storage-controller designs
3D NAND flash memory
Xtacking fabricates the NAND array and peripheral circuits on separate wafers before bonding them. YMTC uses this architecture for TLC and QLC 3D NAND. The flash supplies the storage media; a compatible external controller and firmware handle error correction, bad blocks and data placement.
Managed flash for embedded hosts
eMMC embedded storage
YMTC EC150 combines NAND flash and a controller behind an eMMC 5.1 interface. It stores operating software, applications and retained data in an embedded device. The host uses eMMC commands and boot modes while the device controller manages the NAND media.
Storage for mobile and smart devices
UFS embedded storage
YMTC UFS 2.2 and UFS 3.1 devices combine NAND management with a serial link to the application processor. They store apps, media and system data in phones, tablets and other smart devices. UFS and eMMC use different host interfaces, so capacity alone does not make the devices interchangeable.
Board and firmware architecture
Raw NAND or managed storage
A smart-terminal design can pair raw NAND with its own storage controller and firmware, or connect a managed eMMC or UFS device to the processor. YMTC supplies products at both boundaries. Raw NAND leaves media management to the system; managed storage puts error correction and block management inside the device. This choice changes the board and software effort before capacity is considered.
Storage for PCs and notebooks
Client solid-state drives
YMTC client SSDs use TLC or QLC NAND with PCIe NVMe interfaces, including PCIe 4.0 and 5.0 families. They store the operating system, applications and files in PCs and notebooks. Physical format and cooling affect installation; sustained-write behavior matters when transferring large files.
Server and data-center storage
Enterprise solid-state drives
YMTC enterprise SSDs include PCIe NVMe and SATA products. A server boot drive, a read-heavy data store and a mixed-workload drive face different write and latency demands. Those workloads guide endurance, form factor and power-loss requirements rather than peak sequential speed alone.
