Citigroup, Credit Suisse and JP Morgan are planning an August listing for the flotation of Qimonda, a Munich-based memory chip maker that could raise more than $1.25bn (€1bn).

The company is to list on the New York Stock Exchange in the second week of August, according to Reuters. Boersen-Zeitung, a German newspaper, said that 25% of the share capital would be offered to US institutional investors.
