With the rapid evolution of semiconductor technology, the capacity of mobile ROM has also advanced significantly. Nowadays, flagship smartphones hardly ever feature 16GB ROM, and the recently released iPhone 8/iPhone 8 Plus has also eliminated the 32GB version, starting directly from 64GB. As the capacity of system firmware, apps, and various files continues to increase, … Read more
The address-specified write function supports EMMC_AUTO_ISP (flying line programming), EMMC_AUTO (offline 8x programming), EMMC_AUTO_4BIT (offline socket 4x programming), and EMMC_AUTO_1BIT (offline socket 1x programming). The operation methods for several programming modes are the same, and we will take EMMC_AUTO as an example to introduce the “custom address writing” function. After selecting the EMMC_AUTO function, click … Read more
Introduction to EMMC Circuits EMMC (Embedded Multi Media Card) is a standard specification established by the MMC Association, primarily targeting embedded storage for products such as mobile phones and tablets. EMMC integrates a controller within the package, providing a standard interface and managing flash memory.The principle circuit’s 8-bit data signals are shown in Figure 8-38, … Read more
Compared to UFS flash storage, eMMC has weaker performance. The mixed use of these two types of flash storage in the same model of phone has left some consumers dissatisfied. In response, manufacturers claim that through optimization, eMMC products can also provide an excellent experience. What exactly does this optimization entail? Based on previous promotions, … Read more
