What key details about khaba  can be extracted from the following bio?  Bio: khaba -lrb- also read as hor-khaba -rrb- was a pharaoh of ancient egypt , active during the 3rd dynasty of the old kingdom period . the exact time during which khaba ruled is unknown but may have been around 2670 bc . king khaba is considered to be difficult to assess as a figure of ancient egypt . his name is archaeologically well-attested by stone bowls and mud seal impressions . khaba 's reign is securely dated to the third dynasty . because of the contradictions within ramesside king lists and the lack of contemporary , festive inscriptions , his exact chronological position within the dynasty remains disputed . these problems originate in part from contradictory king lists , which were all compiled long after khaba 's death , especially during the ramesside era . it is also a matter of debate as to where khaba might have been buried . many egyptologists and archaeologists propose that an unfinished step pyramid at zawyet el ` aryan , known as the layer pyramid , belongs to him . others believe instead that his tomb is a large mastaba close to the layer pyramid , where numerous stone vessels bearing khaba 's serekh have been found .
