Inand, onenand

Inand is a small, easy-to-integrate high-speed NAND Flash SD interface chip. Embedded flash memory is a popular storage solution for high-end consumer electronic products such as MP4 players, GPS communication devices, personal media players, and mobile phones. SanDisk inand is a complete sub-system that integrates a serial controller and high-speed nand flash memory on a single device. The inand controller saves the CPU and RAM buffer of the primary system, ensures high reliability and provides a complete disk-type file management structure. It is equipped with an industry-accepted SD serial interface, and SanDisk inand can run on the same bus as the SD card

Onenand is a storage chip based on the NAND structure, which integrates the SRAM cache and logic interface. It integrates advanced NAND flash storage functions and features fast nor flash reading.

Onenand is an embedded storage used to consume electronics, mobile phones, and storage markets.

Important features

• Nand-based structure
• Integrated Ram Buffer
• Nor Interface

System advantages

• Similar to nor, it is easy to detect
• Because of the embedded RAM cache, you can use the xip function for quick start.
• Data and code storage
• The best solution for code ing and command page downloading pages to DRAM with extremely high read Throughput
• Nand high-speed reading
• Embedded hardware ECC and fast data management multi-block Erasure
• Protects the locking mechanism of operating system images and System Data

  Data in NAND Flash is stored in the memory cell in bit mode. Generally, only one bit can be stored in a cell. These cells, in 8 or 16 units, are connected to bit line to form the so-called byte (X8)/Word (x16), which is the location width of the NAND device. These lines form a page.
