Implementing fault tolerant page stripes on low density memory systems

A method, comprising:

• receiving, by a processing device of a memory sub-system controller, a first host data item;
• storing 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;
• receiving a second host data item;
• storing 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 at least a dummy wordline storing no host data;
• storing, in a page of a second logical unit of the memory device, redundancy metadata associated with the fault tolerant stripe.

A non-transitory computer-readable storage medium comprising executable instructions which, when executed by a processing device, cause the processing device to perform operations, comprising:

• receiving a first host data item;
• storing 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;
• receiving a second host data item;
• storing 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 at least a predetermined number of wordlines;
• storing, in a page of a second logical unit of the memory device, redundancy metadata associated with the fault tolerant stripe.
