FAE Expert Insights
"The X4-9070 is a game-changer in the 3D NAND market. In my experience deploying this in enterprise SSD designs, the 232-layer technology delivers exceptional density - we're seeing up to 8TB in a single M.2 2280 form factor. The 1600MT/s interface speed enables sequential read speeds exceeding 7GB/s when paired with a capable controller. I particularly appreciate the improved power efficiency from the center X-DEC design - about 15% lower active power compared to previous generations. The 5,000+ P/E cycle endurance is competitive with industry leaders. For data center applications requiring high capacity and performance, the X4-9070 offers excellent value. I recommend ensuring your controller supports Toggle DDR 4.0 to fully leverage the 1600MT/s interface."

Frequently Asked Questions
What is the storage capacity per die for X4-9070?
The X4-9070 is available in multiple densities: (1) 512Gb (64GB) per die - optimized for cost-sensitive applications; (2) 1Tb (128GB) per die - maximum density for high-capacity SSDs. A single 1Tb die can store 128GB of user data. For SSD applications, multiple dies are stacked in a package to achieve higher capacities - typical configurations include 4-die (512GB), 8-die (1TB), and 16-die (2TB) packages. The 1Tb die enables M.2 SSDs up to 8TB capacity in standard 2280 form factor.
Choose 512Gb for cost optimization; choose 1Tb for maximum density applications.
What is the program and read latency of X4-9070?
The X4-9070 delivers competitive latency performance: (1) Page program time - typical 400-500µs for TLC programming; (2) Page read time - typical 50-60µs for single-page read; (3) Block erase time - typical 3-5ms. These latencies translate to SSD-level performance of: random read 4KB IOPS up to 1M, random write 4KB IOPS up to 400K, sequential read up to 7GB/s, sequential write up to 6GB/s (depending on controller and over-provisioning). The center X-DEC design reduces RC delay, improving access times compared to edge-decoded architectures.
Expect SSD-level performance with sub-100µs read latency and competitive program/erase times.
Does X4-9070 support advanced features like ONFI EZ-NAND?
Yes, the X4-9070 supports advanced ONFI features: (1) EZ-NAND - simplifies controller design by handling complex NAND management internally; (2) Volume addressing - enables flexible die selection and management; (3) Multi-plane operations - allows parallel program/erase in multiple planes for higher throughput; (4) Read cache - enables pipelined read operations for improved performance; (5) Program cache - allows pipelined program operations. These features enable SSD controllers to achieve optimal performance and reliability. Contact LiTong FAE for detailed feature support and implementation guidance.
X4-9070 supports modern ONFI features for simplified controller design and optimal performance.
What is the data retention specification for X4-9070?
The X4-9070 data retention specifications: (1) Standard retention - 10 years at 40°C for fresh data; (2) End-of-life retention - 1 year at 40°C after endurance cycling; (3) Temperature acceleration - retention decreases with higher temperatures, following Arrhenius behavior; (4) Read disturb - minimal impact with proper wear leveling and read scrubbing. For enterprise applications, YMTC recommends periodic read scrubbing and maintaining spare blocks for data refresh. The 232-layer technology with improved cell structure provides robust data retention characteristics competitive with industry standards.
10-year retention at 40°C for fresh data; implement read scrubbing for long-term data integrity.
Is X4-9070 available in automotive grade?
Yes, the X4-9070 is available in AEC-Q100 qualified automotive grade: (1) Temperature grade - available in Grade 2 (-40°C to +105°C) and Grade 3 (-40°C to +85°C); (2) Enhanced testing - additional screening for automotive reliability requirements; (3) Traceability - full lot traceability for automotive quality systems; (4) PPAP support - complete documentation for automotive approval. Automotive grade X4-9070 is suitable for infotainment systems, ADAS storage, digital clusters, and autonomous driving platforms.
