Abstract

An example memory sub-system comprises: a memory device; and a processing device, operatively coupled with the memory device. The processing device is configured to: receive a first host data item; store the first host data item in a first page of a first logical unit of a memory device, wherein the first page is associated with a fault tolerant stripe; receive a second host data item; store the second host data item in a second page of the first logical unit of the memory device, wherein the second page is associated with the fault tolerant stripe, and wherein the second page is separated from the first page by one or more wordlines including a dummy wordline storing no host data; and store, in a third page of a second logical unit of the memory device, redundancy metadata associated with the fault tolerant stripe.
