-## eMMC
-
-Helios64 use the Samsung KLMAG1JETD-B041 chip, this storage has features:
-
- - embedded MultiMediaCard Ver. 5.1 compatible.
- - SAMSUNG eMMC supports features of eMMC5.1 which are defined in JEDEC Standard.
- - Major Supported Features : HS400, Field Firmware Update, Cache, Command Queuing, Enhanced Strobe Mode, Secure Write Protection, Partition types.
- - Non-supported Features : Large Sector Size (4KB).
- - Backward compatibility with previous MultiMediaCard system specification (1bit data bus, multi-eMMC systems).
- - Data bus width : 1bit (Default), 4bit and 8bit.
- - MMC I/F Clock Frequency : 0 ~ 200MHz
- - MMC I/F Boot Frequency : 0 ~ 52MHz
-
-SAMSUNG eMMC adopts Enhanced User Data Area as Single-Level Cell (SLC) Mode.
-Therefore when master adopts some portion as enhanced user data area in User Data Area, that area occupies double size of original set up size. (ex> if master set 1MB for enhanced mode, total 2MB user data area is needed to generate 1MB enhanced area).
-
-The eMMC chip installed in Helios64 support the HS400 MODE, with following features:
-
- - eMMC 5.1 product supports high speed DDR interface timing mode up to 400MB/s at 200MHz with 1.8V I/O supply.
- - HS400 mode supports the following features:
- - DDR Data sampling method
- - CLK frequency up to 200MHz DDR (up to 400Mbps)
- - Only 8-bits bus width available
- - Signaling levels of 1.8V
- - Six selectable Drive Strength (refer to the table below)
-
-Following table describe the I/O Driver Strength Types
