Data erase using a mapping table update in a host device with flash memory system

An apparatus, comprising:

• a memory controller of a memory device:
• coupled to a memory module through a first channel and configured to access data stored in the memory module through the first channel;
• and
• coupled to a host device through a first interface and configured to communicate with the host device over the first interface,
• the memory controller configured to perform operations comprising:
• receiving, by the memory controller of the memory device, a command from the host device as part of a command UFS Protocol Information Unit (UPIU), the command UPIU comprising an invalidated logical block address of a mapping table in the host device corresponding to data to be erased, wherein the command from the host device is a command to update a corresponding logical block address in a memory device mapping table in the memory device;
• and
• transmitting, by the memory controller of the memory device, an indication confirming the memory device mapping table in the memory device has been updated based on the command transmitted from the host device.
