Excited about the HUAWEI P20 Pro? You may have to wait a while longer! Sources tell us that HUAWEI recalled over 60,000 of their P20 Pro smartphones after they shipped with real ROM!
The HUAWEI P20 Pro Recall
However, a large number of the P20 Pro had to be recalled after HUAWEI discovered that they shipped with real ROM, instead of regular flash memory. In a way, these 60,000 HUAWEI P20 Pro smartphones made history by being the first smartphones to actually shipped with real ROM chips!
HUAWEI traced the fault to a manager at their flash memory supplier who took their order for ROM chips too literally. They shipped actual ROM chips to them, instead of eMMC / UFS NAND chips that smartphones use.
The unnamed manager defended his action, pointing out that even HUAWEI’s website clearly states that the P20 Pro comes with ROM, and not regular NAND flash memory chips.
We checked, and true enough, the HUAWEI website officially lists that the HUAWEI P20 Pro comes with 128 GB ROM.
The moral of this story – STOP CALLING FLASH MEMORY ROM!!!
ROM versus Flash
ROM is short for Read Only Memory. The most basic ROM chip has its data programmed during its manufacture, and cannot be deleted or edited. ROM chips are useful because they are non-volatile – they retain their data even when power is cut.[adrotate group=”2″]
Newer ROM chips can be reprogrammed, but only slowly and with some difficulty – the entire chip must be erased before being overwritten. They are mostly used to store computer firmware that are not changed very often.
Flash memory, which is used as smartphone storage and in computer solid state drives, is also non-volatile. But their data can be replaced on a block-by-block basis, allowing them to be used as storage devices.
In short – smartphones do NOT use ROM chips for storage. They use flash memory chips!
