Detailed Specs

Memory Organization

S34ML08G101TFA and S34ML08G101TFI both use a single-level cell (SLC) NAND Flash structure. Each chip stores 8 gigabits of data, organized as 1 gigabit by 8 bits. This means the memory divides into eight data lines, which allows for fast parallel data access. The chips use a page-based architecture. Each page holds a set amount of data, and several pages form a block. This structure helps with efficient data management and supports high-speed read and write operations.

Note: SLC NAND Flash stores one bit per cell, which increases reliability and endurance compared to multi-level cell designs.

Performance and Voltage

Both chips operate within a voltage range of 2.7 to 3.6 volts. This range supports compatibility with many embedded systems and controllers. The typical page program time is about 25 microseconds, which allows for quick data writing. Block erase times also remain short, supporting fast memory management. The parallel ONFI-compliant interface ensures high data transfer rates and smooth integration with standard controllers.

• Operating voltage: 2.7 V to 3.6 V

• Page program time: ~25 µs

• Fast block erase and read speeds

Reliability Features

Engineers rely on these chips for their strong reliability features. Both models include built-in error correction code (ECC), which detects and corrects data errors. Wear-leveling technology spreads out write and erase cycles, which extends the chip’s lifespan. Bad block management identifies and isolates faulty memory blocks, keeping data safe and accessible.

These features make S34ML08G101TFA and S34ML08G101TFI suitable for demanding environments where data integrity matters most.
