I. Comprehensive Overview of Mingjiada Electronics’ Memory IC Product Range
Mingjiada Electronics has long supplied three core product categories: DRAM, NAND Flash and NOR Flash. It also covers eMMC, UFS, SSD, HBM (High Bandwidth Memory) and specialised memory types such as EEPROM and F-RAM, encompassing a wide range of specifications and models to meet the demands of diverse application scenarios.
1. DRAM (Dynamic Random Access Memory)
Mingjiada Electronics supplies the full range of DDR3, DDR4 and DDR5 products from brands such as Samsung, Micron and SK Hynix, whilst also covering LPDDR4 and LPDDR5 low-power memory, GDDR6 and GDDR6X graphics memory, and HBM high-bandwidth memory. Specifically, these include:
Standard DDR series: DDR3, DDR4 and DDR5 memory chips and modules, suitable for servers, PCs and industrial control systems. Representative models include the M393A4K40EB3-CWE (32GB DDR4 3200MHz server memory) and the K4B4G0846E-BCMA (4Gb DDR3 chip).
Low-power LPDDR series: LPDDR4/LPDDR5 series, optimised for mobile applications such as smartphones and wearable devices. Representative models include the KM2L9001CM-B518 (LPDDR5 uMCP).
HBM (High Bandwidth Memory): We supply SK Hynix HBM3E (with a bandwidth of up to 1.18 TB/s) and Samsung HBM2E (KHAA84901B-JC17), meeting the demands of scenarios such as AI training and high-performance computing (HPC).
GDDR graphics memory series: GDDR6/GDDR6X high-bandwidth, low-latency products, suitable for graphics processing applications such as graphics cards and gaming consoles.
Automotive-grade DRAM: High-reliability DRAM products from manufacturers such as Infineon, compliant with the stringent standards of automotive electronics and aerospace.
2. DDR4 SDRAM ETT Memory Chips
Mingjiada Electronics has long supplied DDR4 SDRAM ETT memory chips from leading international brands such as Samsung and SK Hynix, providing cost-effective storage solutions for servers, network communications, industrial control and consumer electronics. ETT (Effective Tested Test) refers to chips that have passed the original manufacturer’s basic functional tests. Compared to UTT (Untested Test), they offer more reliable quality assurance whilst providing a greater cost advantage than the manufacturer’s Major-grade chips. They are particularly suitable for mid-to-high-end equipment applications that have basic storage capacity requirements whilst needing to control BOM costs.
Key supply models include:
Samsung K4A4G165WF-BCWE: 4Gb capacity, 3200Mbps speed, suitable for smart TVs and networking equipment
Samsung K4A8G165WB-BCRC: 8Gb capacity, 2400Mbps speed, suitable for desktop/laptop memory and industrial-grade servers
SK Hynix H5AN8G8NDJR-XNC: 8Gb capacity, high stability; suitable for consumer electronics, industrial control and automotive electronics
SK Hynix H5ANAG6NCJR-XNC: 16Gb high capacity, 3200Mbps high data rate; suitable for servers and industrial control equipment
3. NAND Flash Series
Mingjiada Electronics supplies a full range of NAND flash products covering SLC, MLC, TLC and QLC types, including 3D NAND, eMMC, UFS and SSD categories. From consumer-grade to industrial-grade and automotive-grade applications, these products comprehensively meet the requirements for storage density, read/write speeds and reliability across various scenarios.
SLC/MLC/TLC NAND: Covering cutting-edge technologies such as Micron’s 232-layer 3D NAND TLC and Samsung’s V-NAND, with enterprise-grade SSD capacities reaching up to 61.44TB.
eMMC embedded storage: Supplies models such as the Samsung KLMAG1JETD-B041 (128GB eMMC 5.1), which integrates a controller and flash memory, suitable for smartphones, tablets and automotive electronics.
UFS High-Speed Storage: We offer high-performance products such as the Samsung KLUDG4UHYB-B0EP (128GB UFS 3.1), with bandwidths of up to 6Gbps, meeting the demands of 5G mobile phones and AI devices.
Enterprise-Grade SSDs: Supporting PCIe Gen5/NVMe protocols, with read and write speeds of up to 12GB/s and 5GB/s respectively, suitable for data centres and cloud computing.
4. NOR Flash Memory
Mingjiada Electronics supplies code-based flash memory such as Infineon’s SEMPER™ automotive-grade series, Winbond’s W25Q series, Macronix’s MX25 series and GigaDevice’s GD25 series. These support eXecute-in-Place (XIP), feature fast boot-up and high reliability, and are widely used in embedded systems such as home appliance controls, network communication modules, IoT terminals and automotive electronics for storing boot code and application parameters.
5. Specialised Memory
Mingjiada Electronics also supplies specialised and non-volatile memory such as F-RAM (ferroelectric memory), EEPROM, SRAM/PSRAM and nvSRAM, whilst simultaneously covering niche and hard-to-source models. F-RAM offers unlimited read/write cycles and ultra-low power consumption, making it suitable for high-frequency data logging scenarios; EEPROM is used to store configuration parameters and small amounts of data, and is widely used in household appliances and automotive ECUs; SRAM/PSRAM provides high-speed caching and real-time data processing solutions; nvSRAM combines the speed of SRAM with non-volatility to meet critical data retention requirements.
