STT-MRAM array with 1T1MTJ bitcells, write drivers, reference cells and sense amplifiers, with an ECC-protected controller interface.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
Interfaces
| Port | Direction | Kind | Width | Notes |
|---|---|---|---|---|
| ctrl | in/out | APB control bus | 32 | Control and status registers, including ID, VERSION and STATUS |
| irq | out | interrupt | 1 | Interrupt request |
| port_a | in | valid-qualified bus | 64 | |
| rdata | out | parallel | 64 |
