Thread-local allocation buffer. Used to allocate heap space quickly without synchronization. Compiled code has a "fast path" of a few instructions which tries to bump a high-water mark in the current thread's TLAB, successfully allocating an object if the bumped mark falls before a TLAB-specific limit address.
