Packet-Based One-Time Programmable Memory

원문 (중국어)

A one-time programmable (OTP) memory may be coupled to an OTP memory controller. The OTP memory controller may be configured to store OTP data in a packet format within the OTP memory. Data within the OTP packets may identify respective indices, where each of those indices may correspond to a configuration register or other volatile memory location. The data may be written to the OTP memory during a manufacturing process. During a boot or a reset, the OTP memory controller, in conjunction with a boot loader, may read out data from the OTP memory and cause that data to be written to locations in volatile memory according to the respective indices. After the data has been written to volatile memory, the data may be used to affect a trim of a component, support memory repair techniques, be used as a security key, etc.
