eMMC 5.0 Memory Model

Specification Support

Supports the eMMC 5.0 and 5.1 specification

Product Highlights

General model features
Description
Common queuing
Enhanced strobe in HS400 mode
Cache barrier
CID/CSD/OCR/Ext_CSD registers Implements register bit definitions for a subset of eMMC standard bit definitions.
High capacity negotiation For devices larger than 2GB, the addressing mechanism is switched from byte addressing to sector addressing.
Initialization checks Checks for proper initialization sequence. This check can be skipped.
Supports eMMC command/response protocol Implements 48 bit input command format and R1, R1b, R2, etc. response formats.
State machine and timing checks Implements internal eMMC state machine and performs specified timing checks.
Voltage range checking As part of the CMD1 operation, the model will implement voltage range negotiation.
