Before further detailed description of the embodiments of the present application, terms and expressions referred to in the embodiments of the present application will be described, and the terms and expressions referred to in the embodiments of the present application will be used for the following explanation.
An EMMC (Embedded multimedia Media Card) chip is a mainstream external memory of an Embedded ARM system, and is mainly used for storing images and configuration files and for starting and working the ARM system.
Specifically, an EMMC controller in a main Controller (CPU) is used for controlling an EMMC chip and realizing a data read-write function, the EMMC controller needs driving software to control, and the control method of the working mode of the memory in the application can be an improvement on the driving software of the EMMC controller.
The EMMC working mode comprises the following modes: legacy SDR (traditional single rate mode), High Speed SDR (High Speed single rate mode), DDR52 (double rate 52MHz mode), HS200 (High Speed 200 megabytes per second mode), HS400 (High Speed 400 megabytes per second mode);
specifically, each mode specifically includes the following data:
(1) legacy SDR mode: at this time, the clock frequency is 26MHz, the maximum read-write rate is 26MB/s, and the read-write data is only sampled at the rising edge of the working clock.
(2) High Speed SDR mode: at this time, the clock frequency is 52MHz, the maximum read-write rate is 52MB/s, and the read-write data is only sampled at the rising edge of the working clock.
(3) DDR52 mode: at this time, the clock frequency is 52MHz, the maximum read/write rate is 104MB/s, and the read/write data are sampled at the rising edge and the falling edge of the working clock simultaneously.
(4) HS200 mode: at this time, the clock frequency is 200MHz, the maximum read-write rate is 200MB/s, and the read-write data is only sampled at the rising edge of the working clock.
(5) HS400 mode: at this time, the clock frequency is 200MHz, the maximum read-write rate is 400MB/s, and the read-write data are sampled at the rising edge and the falling edge of the working clock simultaneously.
Specifically, the EMMC has five working modes, from Legacy SDR mode, High Speed SDR mode, DDR52 mode, HS200 mode to HS400 mode, where the performance increases and the stability decreases sequentially, for example, Legacy SDR has the highest stability and the lowest performance; the HS400 mode has the lowest stability but the highest performance. And the read and write speeds are sequentially changed from the low speed mode to the high speed mode.
In addition, the higher the read/write rate, the worse the stability performance of the operating mode with increasing temperature.
