Alliance Memory ASFC Series 5.1 e·MMC

Alliance Memory ASFC Series 5.1 e·MMC is a compact storage solution with a single-chip MMC controller and NAND flash memory. Alliance Memory ASFC is designed for data storage and booting, prioritizing efficient read operations at low power. 3D TLC NAND technology offers an Enhanced mode (pSLC) for demanding industrial use, supported by an industrial temperature grade specification. The e·MMC controller handles NAND flash management, including ECC, wear-leveling, IOPS optimization, and read sensing. The device supports high throughput for large data transfers and excels in handling small random data often found in code. Additionally, it includes security features, multiple boot partitions, and advanced refresh for read-intensive applications. Communication is facilitated via an 11-signal bus, following the JEDEC e·MMC standard known as e·MMC mode.

Features

Optimized FW algorithms
- Power-fail data loss protection
- Wear Leveling technology
  - Equal wear leveling of static and dynamic data
  - The wear leveling assures that dynamic data, as well as static data, is balanced evenly across the memory
  - With that, the maximum write endurance of the device is ensured
- Read Disturb Management
  - The read commands per region are monitored, and the content is conditionally refreshed when critical levels have occurred
- Auto Read Refresh
  - The interruptible background process maintains the user data for Read Disturb effects or Retention degradation due to high-temperature effects
- Diagnostic features with Device Health Report according to e·MMC Spec 5.1, and detailed Lifetime
  - Monitor data (Alliance proprietary, accessible through standard e·MMC commands)
- Field firmware update according to e·MMC Spec 5.1
- Discard and sanitize, trim
- Boot operation mode and alternative boot operation mode
- Replay Protected Memory Block (RPMB)
