用語(terms)
| term | Description |
|---|---|
| BndM | Bulk Non-Volatile Data Manager |
| ECC | Error Correction Code |
| FOTA | Firmware Over The Air - remote firmware update using wireless communication |
| HSM | Hardware Security Module - dedicated security MCU core |
| OTA | Over The Air - general term for wireless communication between OEM backend and vehicle |
| RWW | Read While Write - capability of a memory device to perform a read operation in one memory bank while at the same time a write/erase operation takes place in another bank |
| SOTA | Software Over The Air - remote software update using wireless communication |
| Address Area | Contiguous memory area in the logical address space Typically multiple physical memory sectors are combined to one logical address area. |
| Bank | Group of sector batches. In case a memory technology is segmented in sectors, a bank is an instance of a sector batch group in which no read-while-write operation is permitted. In case of a flash memory device, this typically maps to an individual flash controller. |
| Job Request | Memory access request by an upper layer module for an address area. |
| Memory Device | Group of banks |
| Page Burst | Aggregated access of memory pages for improved performance In case a memory device technology has a physical segmentation, some memory devices provide an optimized access method to read or write multiple pages at a time. Page burst denotes the aggregation of memory pages used for the access optimization. |
| Read Page | Smallest readable unit of a memory device (in bytes) Some memory device technologies must be accessed considering a physical segmentation. Hence a byte-wise access is not possible for all memory device technologies. This term defines the minimum size that needs to be read in one access. |
| Sector | Smallest erasable memory unit (in bytes) Some memory device technologies require an explicit physical erase operation before the memory can be written. A sector defines the minimum size of such an erase unit. Depending on the memory device, sectors can be either uniform- or variable-sized. |
| Sector Batch | Aggregation of sectors with uniform size Logical aggregation of contiguous sectors with the same size. |
| Sector Burst | Aggregation of sectors for improved erase performance In case a memory technology needs a physical erase operation, some devices provide an erase performance optimization by erasing an aggregation of sectors in one step. |
| Sub Address | Area Contiguous memory area in the logical address space mapped to a sector batch of one memory device. |
| Write Page | Smallest writeable unit of a memory device (in bytes) Some memory device technologies must be accessed considering a physical segmentation. Hence a byte-wise access is not possible for all memory device technologies. This term defines the minimum size that needs to be written in one access. |
