Managed-NAND With Embedded Random-Access Non-Volatile Memory

摘要

Systems and methods embed a random-access non-volatile memory array in a managed-NAND system to execute the boot code or other time-sensitive applications. By embedding this random-access non-volatile memory in the managed-NAND system, either on the memory controller chip or as a separate chip within the managed-NAND system package, an application may be read with fast initial access time, alleviating the slow access time limitations of NAND Flash technology. Depending on the size of the application, the system may be configured to read the whole application content or only a time-critical portion from this embedded random-access non-volatile memory array.

1. A managed-NAND system comprising:
a memory controller comprising at least a microcontroller and a bus interface; at least one NAND memory array coupled to and configured to be controlled by the memory controller; and an embedded random-access non-volatile memory array configured to store code for a boot sequence or time-sensitive applications.
