Small capacity storage “Parallel NAND flash”

   The Internet of Everything (IoT), with the impending data explosion in the 5G era, places more demands on storage chips. The size of electronic items is becoming more compact, and memory chips are moving toward shrinking despite their having richer and more complex functionality. FORESEE, embedded storage brand, introduced NAND Flash devices that satisfy the demands on downsizing and portability of mobile electronic goods after more than 20 years of expertise and technological advancements. It is industry-leading in terms of capacity and performance after several testing and verification.

   Previously, the functionality of electrical items were basic, requiring fewer programmes and codes. On general, programmes did not save in NOR Flash would enough to fulfil the requirements. However, the functionalities of electronic devices are growing more complex and sophisticated, necessitating the use of a greater number of programmes and codes. Because of its tiny capacity and expensive cost per unit of capacity, the NOR Flash no longer matches manufacturing demands. At this critical juncture, the NAND Flash appears. NAND is the most prevelant type of flash memory. It is found in a variety of storage devices, including as SSDs, USB flash drives, and SD cards. NAND memory is non-volatile, which means it preserves data even when power is switched off.

   Typical parallel NAND Flash small-capacity devices vary from 1Gb to 4Gbe. Parallel NAND Flash provides the high storage capacity and performance required for multimedia data storage applications on mobile devices, set-top boxes, data cards, TVs, and other devices.

   Memory cards, USB flash drives, and solid-state drives are the most common uses for NAND. Parallel NANDFlash is everywhere - in cellphones, current televisions, and laptops and tablets in homes and businesses. Outside, it may be found in anything from traffic lights to digital advertising panels, passenger announcement systems, and displays. Parallel NAND Flash is likely to be found in anything that contains artificial intelligence (AI) and needs to transport and preserve data.

   To transport data, addresses, and instructions, NAND Flash devices employ a highly multiplexed 8- or 16-bit bus (I/O[7:0] or I/O[15:0]). The NAND command bus interface protocol is implemented via the five command pins (CLE, ALE, CE#, RE#, WE#). Three more pins are used to manage hardware write protection (WP#), device status (R/B#), and the auto-read capability (PRE—3V device only).

Advantages

  Devices using NAND Flash are mechanical shock resistance, high durability and are able to withstand high pressure and temperature when compared to traditional hard disk drives. There are no moving parts, unlike HDDs, so are ideal for systems that vibrate and shake. NAND also provides rapid read access times, which is important for processing large amounts of data.

· OTP, UID, and Array Protection are all security features as per unit of capacity than NOR Flash.

More Advanced 16nm Process

  Most NAND Flash devices on the market today employ a 2X to 3Xnm technology, but FORESEE uses a 16nm process with greater technological edges. Meanwhile, the built-in ECC (4 bit/512 Bytes) unit eliminates the need for an MCU that functions as either hardware or software ECC, and reduces the needs for the Host's hardware error-correcting capacity. As a result, the absence of a traditional NAND controller reduces the Host's expenses.

Performance Enhancement in Multiple Directions

The data transmission efficiency is considerably increased because to the high clock rate, 108 MHz quick access, and four-channel I/O data transmission rate of up to 432 Mbit/s.

The 2K-byte high-speed cache improves the access performance of the parallel NAND Flash and enables fast random access.

Increased Secure Storage Space

  Software encryption based on the unique ID of chips may be performed with a 20K-byte One Time Programmable (OTP) region where data is not erasable. Furthermore, the 20K byte OTP regions, which are bigger than the standard 16K byte ones, provide extra space for securely storing information.

Outlook

  FORESEE parallel NAND Flash solutions are currently extensively utilized in a variety of industries and have demonstrated good performance when used in PON, DVB, IPC, AI speakers, routers, smart access control, smart hardware, and other products.

The FORESEE micro-storage product family includes the SLC Parallel NAND, DDR, Nand-based MCP, SPI NOR, and T-Flash, in addition to the NAND Flash. Each product has been subjected to rigorous high and low temperature testing, as well as tests for age and wear, program/erase cycles, and general dependability.

FORESEE micro-storage devices have now been AVL verified by 25 major platforms in over 100 major control models. FORESEE small capacity storage solutions have been provided to over 200 clients globally because to their ease of integration, excellent performance, and compatibility.
