We study the problem of memory capacity in balanced networks of spik-
ing neurons. Associative memories are represented by either synfire
chains (SFC) or Hebbian cell assemblies (HCA). Both can be embedded
in these balanced networks by a proper choice of the architecture of the
network. The size wE of a pool in an SFC or of an HCA is limited from
below and from above by dynamical considerations. Proper scaling of
wE by

K, where K is the total excitatory synaptic connectivity, allows
