Resistive crossbar compute-in-memory macro
Maturity plannedTargets ASIC (CMOS) onlyDifficulty Very hardPriority 3
RRAM or PCM crossbar with program and verify circuits, input drivers and sense ADCs for analog in-memory inference.
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 |
| bl_out | out | analog | 64 |
Standards
No external standard applies.
Notes
Requires a back-end-of-line resistive memory option on the target process.
